Description

Technical Field

[0001] The present invention relates to the technical field of mechanical hard disks, and in particular to a deformation adjustment method of a deformable slider of a mechanical hard disk, an electronic device, and a medium. Background Art

[0002] A mechanical hard drive consists of a read / write head, a platter, a voice coil motor that drives the head arm, and a rotor motor that drives the platter. The head arm utilizes the wedge-shaped space between the head slider and the platter to compress air, creating air film pressure, which in turn creates aerodynamic forces that propel the slider over the platter's surface. To maintain head flight, the surface of the slider facing the platter features specialized aerodynamic structures, such as stepped surfaces, shallow grooves, and deep grooves. These structures utilize air pressure to keep the slider suspended above the platter during high-speed rotation, maintaining a minimal gap on the order of nanometers.

[0003] However, the above-mentioned head slider structure is fixed and can only meet the requirements of stable flight under specific environments and working conditions. It may not be able to maintain stability in complex and harsh environments, resulting in abnormal performance or hard disk damage. Although it can be improved by optimizing the design or increasing external environment monitoring and environmental protection, the cost of external environment control is high. Summary of the Invention

[0005] The present invention provides a deformation adjustment method for a deformable slider of a mechanical hard disk, wherein at least one driver is provided on the surface of the deformable slider, and the at least one driver is used to drive the deformation of the deformable slider, comprising the following steps: when the mechanical hard disk is in a working state, collecting environmental data inside the mechanical hard disk, and obtaining the pressure distribution of the deformable slider based on the environmental data; when it is determined that the deformable slider is in an underpressure state or an overpressure state according to the pressure distribution of the deformable slider, determining the deformation compensation amount of the deformable slider according to the pressure distribution of the deformable slider; if the deformation compensation amount is within a preset deformation amount range, using the at least one driver to control the deformable slider to deform according to the deformation compensation amount.

[0006] The present invention also provides a deformation adjustment device for a deformable slider of a mechanical hard disk, wherein at least one driver is provided on the surface of the deformable slider, and the at least one driver is used to drive the deformable slider to deform, including: an acquisition module, used to acquire environmental data inside the mechanical hard disk when the mechanical hard disk is in a working state, and obtain the pressure distribution of the deformable slider based on the environmental data; a determination module, used to determine the deformation compensation amount of the deformable slider according to the pressure distribution of the deformable slider when it is determined that the deformable slider is in an undervoltage state or an overvoltage state according to the pressure distribution of the deformable slider; a deformation adjustment module, used to use the at least one driver to control the deformable slider to deform according to the deformation compensation amount if the deformation compensation amount is within a preset deformation amount range.

[0007] The present invention also provides an electronic device, comprising: a memory for storing a computer program; and a processor for implementing the steps of the deformation adjustment method of the deformable slider of the mechanical hard disk when executing the computer program.

[0010] The present invention collects environmental data within the mechanical hard disk while it is in operation, and based on this environmental data, determines the pressure distribution of the deformable slider. When the deformable slider is determined to be in an underpressure or overpressure state based on the pressure distribution, the deformation compensation amount of the deformable slider is determined based on the pressure distribution of the deformable slider. If the deformation compensation amount is within a preset deformation range, at least one driver is used to control the deformable slider to deform according to the deformation compensation amount. This solves the problem in the prior art that the magnetic head slider structure of mechanical hard disks is fixed, unable to adapt to a wide range of environments, and may not maintain stability in complex environments, resulting in abnormal performance or hard disk damage, and high control costs. This allows hard disks to be applied to a wider range of environmental scenarios, actively and controllably ensuring normal operation. Under abnormal environmental influences, the magnetic head arm can achieve stable flight through self-adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] It should be noted that, in the description of the present invention, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. The terms "first," "second," etc., in the present invention are used to distinguish similar objects, and are not used to describe a particular order or precedence.

[0021] A mechanical hard drive consists of a read / write head, a platter, a voice coil motor that drives the head arm, and a rotor motor that drives the platter. The head arm relies on the wedge-shaped space between the head slider and the platter to compress air, creating air film pressure. This aerodynamic force allows it to fly over the platter surface. To maintain head flight, the surface of the slider facing the platter features specialized aerodynamic structures, such as stepped surfaces, shallow grooves, and deep grooves. These structures utilize the pressure generated by air flow to keep the slider suspended above the platter, maintaining a microscopic gap (on the order of nanometers) during high-speed platter rotation. Therefore, the aerodynamic design of the slider is crucial to ensuring smooth head arm flight. Furthermore, during operation, dust and particles inhaled from the outside or generated internally by a mechanical hard drive can easily cause collision and friction between the head and the platter, damaging them. This can lead to data loss at best and hard drive failure at worst.

[0022] In the prior art, special aerodynamic structures such as stepped surfaces, shallow groove surfaces, and deep groove surfaces are designed to ensure the smooth flight of the magnetic head arm. However, this method has the following disadvantages:

[0023] 1. The structure of the head slider is fixed. The aerodynamic structure of the head slider can only be designed to ensure the stable flight of the head arm under the set environment and working conditions.

[0024] 2. The actual working environment of the hard disk is very complex. If it encounters a harsh or abnormal working environment, it may not be able to maintain the smooth flight of the head arm, resulting in abnormal performance or even collision between the head and the disk, causing damage to the hard disk.

[0025] 3. Existing technologies can only optimize or increase external environment monitoring and environmental maintenance during initial design, but the control of the external environment, especially the temperature response speed, is slow, and maintaining a good environment requires a huge cost.

[0026] To solve the above problem, an embodiment of the present invention provides a method for adjusting the deformation of a deformable slider of a mechanical hard disk.

[0027] like Figure 1 As shown, the deformation adjustment method of the deformable slider of the mechanical hard disk includes the following steps:

[0028] The surface of the deformable slider is provided with at least one driver, and the at least one driver is used to drive the deformable slider to deform.

[0029] This invention uses a smart material-based slider surface structure to dynamically adjust deformation. By sensing changes in the mechanical hard drive's operating conditions in real time, the slider's surface structure is proactively adjusted to maintain stable flight of the magnetic head arm and proper operation of the hard drive. Furthermore, based on collected data such as temperature, humidity, and air pressure patterns and trends, the slider can predict operating condition changes in advance and adjust the surface structure accordingly.

[0030] The present invention includes the following modules: Figure 2 As shown:

[0031] (1) Deformable slider: The deformable slider is made of deformable materials such as piezoelectric ceramics, which can produce nano-level deformation through electrical signal control, and the response speed can reach microseconds. The structure of the deformable slider is as follows: the surface of the head slider is designed to be divided into n independent units, such as grid units, each unit has a separate intelligent material driver for triggering the local deformation of the control material. The structure of the head slider is as follows: Figure 3 shown.

[0032] (2) Working status judgment module: It determines whether the mechanical hard disk is in working state or idle state to select different working modes.

[0033] (3) Environmental perception module: set up head flying height sensor; temperature sensor, humidity sensor, air pressure sensor; vibration sensor.

[0034] (4) Calculation module: Based on the environmental parameter changes sensed by the environmental sensing module sensor, the air film pressure state of each unit on the slider surface can be obtained, and then the deformation of each unit structure that needs to be adjusted to ensure stable flight of the magnetic head arm can be calculated, that is, whether each unit needs to be further convex or reduced.

[0035] (5) Data collection module: For a working mechanical hard disk, except for abnormal short-term vibrations, changes in ambient environmental parameters such as temperature, humidity, and air pressure are all trend changes. Therefore, by predicting environmental changes, the surface structure of the slider can be adjusted in advance to ensure the normal operation of the mechanical hard disk.

[0036] (6) Early warning module: The change and control of the slider surface morphology has a range and an adjustable threshold. When the change of the environmental parameters is large and exceeds the adjustable threshold, an early warning is issued.

[0037] (7) Cleaning function module: When the mechanical hard disk is in an idle state, the slider's special surface morphology structure can be used to quickly discharge and replace the internal gas of the mechanical hard disk, avoiding the internal gas turbidity and other factors that affect normal operation. At the same time, it can also remove the internal dust. When there are particles on the disk that are likely to cause scratches on the magnetic head or disk, the special slider structure of the cleaning function can also generate airflow to the periphery of the disk to remove the particles from the disk.

[0038] Specifically, in step S101 , when the mechanical hard disk is in working state, environmental data in the mechanical hard disk is collected, and the pressure distribution of the deformable slider is obtained based on the environmental data.

[0039] Optionally, in some embodiments, environmental data within the mechanical hard disk is collected, and the pressure distribution of the deformable slider is obtained based on the environmental data, which also includes: collecting current temperature, current humidity, current pressure and vibration data within the mechanical hard disk; and calculating the pressure distribution of the deformable slider using the principles of gas dynamics based on the current temperature, current humidity, current pressure and vibration data.

[0040] When the mechanical hard disk is in normal working condition, the surface structure of the deformable slider will be in an initial default state, which is the default surface morphology. Then, as the environment changes, the morphology will gradually change.

[0041] Specific as Figure 4 As shown, the temperature sensor, humidity sensor, and air pressure sensor are used to collect real-time environmental data in the mechanical hard disk, including current temperature, current humidity, current pressure, and vibration data.

[0042] The calculation module further calculates the environmental parameters such as the current temperature, current humidity, current pressure and vibration data obtained using the principles of gas dynamics to obtain the surface air film pressure distribution of the deformable slider.

[0043] Through the above technical solution, the current temperature, current humidity, current pressure and vibration data inside the mechanical hard disk can be collected in real time, realizing comprehensive and accurate perception of the hard disk working environment. By using the principles of gas dynamics, the pressure distribution of the deformable slider and the pressure distribution of the air film on the surface of the head slider are calculated according to the collected environmental data, providing a theoretical basis for the deformation of the deformable slider.

[0044] Step S102 : when it is determined that the deformable slider is in an underpressure state or an overpressure state according to the pressure distribution of the deformable slider, a deformation compensation amount of the deformable slider is determined according to the pressure distribution of the deformable slider.

[0045] It should be understood that the surface air film pressure of the deformable slider is compared with a set standard pressure range.

[0046] If the surface air film pressure is lower than the lower limit of the set standard pressure range, the deformable slider is judged to be in an underpressure state; if the surface air film pressure distribution is higher than the upper limit of the set standard pressure range, the deformable slider is judged to be in an overpressure state. For example, if the standard pressure range is The calculated surface air film pressure is , it is determined that the deformable slider is in an undervoltage state.

[0047] After further determining whether the deformable slider is in an underpressure state or an overpressure state, the deformation compensation amount of the deformable slider is determined to adjust the working state of the slider.

[0048] Optionally, in some embodiments, if the deformable slider is determined to be in an underpressure state or an overpressure state based on the pressure distribution of the deformable slider, the deformation compensation amount of the deformable slider is determined based on the pressure distribution of the deformable slider, and the method further includes: if the deformable slider is in an underpressure state, the current deformation amount of the deformable slider is increased based on a preset deformation amount increasing strategy to obtain the deformation compensation amount; if the deformable slider is in an overpressure state, the current deformation amount of the deformable slider is reduced based on a preset deformation amount decreasing strategy to obtain the deformation compensation amount.

[0049] It should be understood that if Figure 4 As shown, when the deformable slider is in an under-pressure state, meaning the pressure between the slider and the contact surface is insufficient, a preset deformation increase strategy is used to increase the current deformation of the deformable slider, thereby increasing the pressure between the slider and the contact surface and improving its working condition. This deformation increase strategy can be a fixed incremental increase or a dynamically calculated increment based on the degree of deviation in the pressure distribution, making the slider's deformation adjustment more precise.

[0050] If the deformable slider is in an overpressure state, the pressure between the slider and the contact surface is excessive. Therefore, a preset deformation reduction strategy is needed to reduce the current deformation of the deformable slider and lower the pressure between the slider and the contact surface. This deformation reduction strategy can also be a fixed reduction or dynamically adjusted based on pressure deviation to achieve appropriate adjustment of the slider's deformation.

[0051] Specifically, the flying state of the magnetic head arm is generated by the aerodynamic force (i.e., air film pressure) generated in the space between the magnetic head slider and the disk, which generates a force pushing the magnetic head arm. The magnitude of this force is inversely proportional to the gap between the magnetic head arm and the disk. That is, the smaller the gap, the greater the air pressure. Therefore, when an undervoltage state occurs, the deformation of the magnetic head slider unit needs to be increased to reduce the gap, and vice versa.

[0052] Through the above technical solution, when the deformable slider is in an under-pressure state, the change in air film thickness caused by insufficient pressure can be compensated by increasing the deformation amount, thereby maintaining a stable air film pressure distribution between the head slider and the disk surface, ensuring the stability and reliability of the head during flight, and reducing read and write errors caused by air film pressure fluctuations. When the deformable slider is in an over-pressure state, the air film pressure is reduced by reducing the deformation amount, avoiding excessive contact or collision between the head and the disk surface, protecting the disk data and the head from damage, improving the adaptability of the hard disk, extending the service life of the hard disk, and optimizing the hard disk performance.

[0053] In step S103 , if the deformation compensation amount is within a preset deformation amount range, at least one driver is used to control the deformable slider to deform according to the deformation compensation amount.

[0054] The preset deformation range may be a threshold value pre-set by the user, a threshold value obtained through a finite number of experiments, or a threshold value obtained through a finite number of computer simulations, and is not specifically limited here.

[0055] It is understandable that it is determined whether the deformation compensation amount is within a preset deformation amount range. If it is within the preset deformation amount range, at least one driver is used to control the deformable slider to deform according to the deformation compensation amount.

[0056] Optionally, in some embodiments, after using a driver to control the deformable slider to deform according to the deformation compensation amount, it also includes: detecting the current flight state of the head arm in the mechanical hard disk; if the current flight state of the head arm does not meet the preset stability condition, recalculating the new pressure distribution of the deformable slider, and re-determining the new deformation compensation amount of the deformable slider based on the new pressure distribution of the deformable slider, so as to control the deformation of the deformable slider according to the new deformation compensation amount until the current flight state of the head arm meets the preset stability condition.

[0057] It can be understood that after each unit of the deformable slider is deformed, a complete surface topography structure is obtained.

[0058] It is further necessary to specifically determine whether the current flight state of the magnetic head arm meets the preset stability conditions. The specific steps are as follows:

[0059] The flying height sensor, attitude measurement sensor and vibration sensor are used to collect the flying height, attitude angle and vibration amplitude of the head arm respectively.

[0060] The collected data is processed and analyzed in real time to calculate the flying height, attitude angle and vibration amplitude of the magnetic head arm.

[0061] Determine whether the flying height, attitude angle and vibration amplitude of the head arm are all within the allowable range. If the flying height of the head arm is within the preset range, the tilt angle and azimuth angle of the head are within the preset range, and the vibration amplitude of the head arm is within the preset range, then the head arm is judged to be flying stably. If any of the indicators does not meet the conditions, then the head arm is judged to be flying unstable.

[0062] When the flying state of the magnetic head arm is still unstable, it is necessary to obtain the surface pressure of the deformable slider again, recalculate the new deformation compensation amount, and deform again according to the new deformation compensation amount until the magnetic head arm runs smoothly.

[0063] Through the above technical solution, the flight status of the magnetic head arm in the mechanical hard disk is detected in real time. Once it is found that it does not meet the preset stability conditions, the adjustment mechanism is immediately activated. This real-time monitoring and adjustment capability ensures that the magnetic head arm always remains in the best working condition, improving the read and write accuracy and stability of the hard disk.

[0064] Optionally, in some embodiments, after detecting the current flight state of the head arm in the mechanical hard disk, it includes: if the current flight state of the head arm meets the preset stability condition, calculating the deformation prediction value of the deformable slider at the next moment, and sending a deformation failure warning reminder to the preset terminal when the deformation prediction value at the next moment is not within the preset deformation range.

[0065] Specifically, if the current flight state of the head arm meets the preset stability conditions, it is necessary to predict the working condition of the mechanical hard disk at the next moment, and then calculate the predicted deformation of each unit of the deformable slider required to ensure the normal operation of the mechanical hard disk at the next moment, so as to achieve early intervention.

[0066] If the predicted deformation at the next moment is not within the preset deformation range, an undeformable warning reminder will be sent to the preset terminal for early warning.

[0067] Through the above technical solution, when the flight state of the head arm is stable, the predicted deformation of the deformable slider at the next moment is calculated, which realizes the early prediction of possible deformation in the future, and helps to take measures before potential problems occur. When the predicted deformation exceeds the preset range, an early warning reminder of the inability to deform is sent to the preset terminal in time, so that the user can understand the possible risks of the hard disk in advance and take corresponding preventive measures, such as backing up data, arranging hard disk replacement, etc., to improve the reliability of the hard disk.

[0068] Optionally, in some embodiments, the predicted deformation amount of the deformable slider at the next moment is calculated, including: establishing a function model of environmental parameters changing with time based on historical environmental data of the mechanical hard disk; predicting the environmental parameters of the mechanical hard disk at the next moment according to the function model of environmental parameters changing with time; and obtaining the predicted deformation amount of the deformable slider at the next moment based on the environmental parameters of the mechanical hard disk at the next moment.

[0069] Specifically, a function model of environmental parameters changing over time is established based on the historical environmental data of the mechanical hard disk. Since the changes in parameters of the mechanical hard disk's external environment, such as temperature, humidity, and air pressure, are often continuous and regular, it is very reliable to establish a function model of environmental parameters changing over time to predict future parameter changes. Therefore, after recording the historical environmental data, the range of environmental parameter changes at the next moment can be calculated, thereby inferring the predicted deformation of the deformable slider at the next moment.

[0070] Through the above technical solution, a function model of environmental parameters changing over time is established based on the historical environmental data of the mechanical hard disk, which can more accurately reflect the actual change law of the environmental parameters, thereby improving the prediction accuracy of the environmental parameters at the next moment, and then accurately calculating the deformation prediction amount of the deformable slider.

[0071] Optionally, in some embodiments, when the deformation compensation amount is not within a preset deformation amount range, the method further includes: sending a deformation failure warning reminder to a preset terminal.

[0072] It is understandable that when the deformation compensation amount is not within the preset deformation range, a warning is issued in a timely manner. This is because even if environmental parameters change, the mechanical hard disk has a short-term fault tolerance mechanism and will not immediately report errors. However, if a certain amount of errors accumulates in an abnormal environment, the mechanical hard disk may be damaged or data lost. Therefore, when the deformation compensation amount is detected to be outside the preset deformation range, the system cannot control the head arm to operate smoothly, and an immediate warning is required. Human intervention can prevent further damage to the mechanical hard disk.

[0073] Through the above technical solution, when the deformation compensation amount exceeds the preset deformation range, that is, when an environmental abnormality is detected and has exceeded the hard disk's own adjustable threshold, the system can immediately send an undeformable warning reminder to the preset terminal, ensuring that the user can understand the abnormal status of the hard disk in a timely manner and take intervention measures quickly.

[0074] Optionally, in some embodiments, when sending the deformation-impossible warning reminder to the preset terminal, it includes: using a preset alarm component to perform an acoustic alarm reminder and / or an optical alarm reminder.

[0075] Specifically, when the deformation compensation amount of the deformable slider is not within the preset deformation range, it means that the system cannot make the head arm run smoothly by adjusting the deformation. At this time, an early warning reminder should be sent to the preset terminal in time. The combination of acoustic alarm and optical alarm can effectively ensure that the early warning information is accurately conveyed. Among them, the preset alarm component includes an acoustic alarm unit and / or an optical alarm unit, and technical personnel in this field can flexibly configure it according to actual needs.

[0076] Through the above technical solution, through acoustic alarm reminders and / or optical alarm reminders, and through clear acoustic and optical signals, users' misjudgment or neglect of early warning signals can be reduced, ensuring that early warning information can be accurately conveyed to users, and improving the reliability and effectiveness of early warnings.

[0077] Optionally, in some embodiments, the preset alarm component includes an acoustic alarm unit and / or an optical alarm unit, and the preset alarm component is used to perform an acoustic alarm reminder and / or an optical alarm reminder, including: using the acoustic alarm unit to output an acoustic signal with a preset frequency, preset volume and preset duration, and / or using the optical alarm unit to output an optical signal with a preset color, preset brightness and preset flashing frequency.

[0078] It should be noted that the preset frequency, preset volume, preset duration, preset color, preset brightness and preset flashing frequency can be thresholds set in advance by the user, can be thresholds obtained through a limited number of experiments, or can be thresholds obtained through a limited number of computer simulations, and are not specifically limited here.

[0079] Specifically, the present invention uses a high-sensitivity, high-quality buzzer as the core component of the acoustic alarm unit. The buzzer can produce clear and loud sound signals, and its internal structure has been optimized to accurately control the frequency, volume and duration of the sound.

[0080] High-brightness, multi-color LED indicators are used as optical alarm units. LED indicators have the advantages of high luminous efficiency, long life, and rich colors. They can convey different warning information through different colors, brightness, and flashing frequencies.

[0081] This technical solution, through the output of an acoustic signal with a preset frequency, volume, and duration, can quickly attract the user's attention, allowing them to immediately perceive abnormal hard drive conditions. The intuitiveness and sense of urgency of the acoustic alarm help users react quickly and take necessary intervention measures. The optical alarm uses an optical signal with a preset color, brightness, and flashing frequency to visually convey warning information. The visual alarm's eye-catching and persistent nature helps users receive the warning signal promptly even from a distance or in noisy environments.

[0082] Optionally, in some embodiments, the deformation adjustment method of the deformable slider of the above-mentioned mechanical hard disk also includes: when the mechanical hard disk is not in a working state, obtaining a cleaning function instruction selected by the user; according to the cleaning function instruction, using the surface morphology structure of the mechanical hard disk to perform air cleaning and / or particle cleaning.

[0083] It is understandable that when the mechanical hard disk is in a non-working state, it obtains the cleaning function instruction selected by the user. According to the cleaning function instruction, the surface morphology structure of the mechanical hard disk is used to realize internal air renewal and particle collection, thereby playing a cleaning role. In this way, when the mechanical hard disk is working normally, it can avoid particles colliding with the head and causing scratches on the head and disk.

[0084] Among them, the specific surface morphology structure of the mechanical hard disk, such as the stepped pressure gradient structure, that is, from the inner circle to the outer circle, the height of each unit decreases successively, forming a pressure gradient along the radial direction of the disc, and there are guide grooves between each unit, which can guide the gas to flow along the gradient direction, thereby removing dust, particles, etc. on the disc from the disc.

[0085] Through the above technical solution, by cleaning the dust and particles inside the hard disk, the risk of scratches on the head and platter caused by particles colliding with the head during operation is reduced, the service life of the hard disk can be extended, the reliability and stability of the hard disk can be improved, and the overall performance of the hard disk can be improved. Users can select the cleaning function through simple instructions without disassembling the hard disk or performing complicated cleaning operations, which improves the convenience of use.

[0086] Furthermore, in some embodiments, after performing air cleaning and / or particle cleaning using the surface morphology structure of the mechanical hard disk, it includes: controlling the mechanical hard disk to enter a working state, and detecting the current flight state of the head arm in the mechanical hard disk; if the current flight state of the head arm does not meet the preset stability conditions, air cleaning and / or particle cleaning are performed again.

[0087] Specifically, after performing air cleaning and / or particle cleaning using the surface topography of the mechanical hard disk, it is necessary to further determine whether the flight of the magnetic head arm is stable.

[0088] Control the mechanical hard disk to enter the working state. If the current flight state of the head arm does not meet any one or more of the preset stability conditions in terms of flight height, attitude or vibration, it is determined that air cleaning and / or particle cleaning are required again. If the current flight state of the head arm meets the preset stability conditions, it is determined that the mechanical hard disk can be put into use at this time.

[0089] Through the above technical solution, after completing air cleaning and / or particle cleaning, the mechanical hard disk is immediately controlled to enter the working state, and the current flight state of the head arm is detected. If the current flight state of the head arm does not meet the preset stability conditions, timely re-cleaning can be used to promptly detect the problem of unstable flight of the head arm caused by particles that may remain during the cleaning process or incomplete cleaning, effectively reducing the risk of hard disk failure caused by unstable flight of the head arm and optimizing hard disk performance and life.

[0090] In order to enable those skilled in the art to further understand the deformation adjustment method of the deformable slider of the mechanical hard disk in the embodiment of the present application, the following is a detailed description with reference to specific embodiments. Figure 5 shown.

[0091] In step S501, the working status of the hard disk is detected.

[0092] In step S502, it is detected whether the hard disk is in working state. If the hard disk is not in working state, steps S514 to S519 are executed; otherwise, steps S503 to S513 are executed.

[0093] In step S503 , if the hard disk is in working state, the deformable slider is in the initial state by default.

[0094] In step S504, the environment sensing module detects the environment data of the hard disk.

[0095] In step S505 , the calculation module determines the air pressure distribution of the deformable slider according to the environmental data.

[0096] In step S506 , the deformation compensation amount of the deformable slider is determined according to the air pressure distribution.

[0097] In step S507 , it is determined whether the deformation compensation amount exceeds a controllable threshold.

[0098] In step S508, if it exceeds, step S513 is executed; if it does not exceed, all units of the deformable slider are controlled to deform.

[0099] In step S509 , the surface topography of the deformed slider is determined.

[0100] In step S510, it is determined whether the magnetic head arm is flying smoothly. If so, step S511 is executed; otherwise, step S505 is executed again.

[0101] In step S511, historical environmental data is collected to predict the deformation of the slider at a future moment.

[0102] In step S512, it is determined whether the deformation prediction amount at the future moment exceeds the controllable threshold. If not, step S511 is continued to be executed; if it exceeds, step S513 is executed.

[0103] In step S513, an early warning is issued.

[0104] In step S514, the user selects a cleaning function through the cleaning function module.

[0105] In step S515, each unit of the deformable slider is controlled to perform a specific deformation.

[0106] In step S516 , the surface of the slider obtains morphologies that meet different functional requirements.

[0107] In step S517 , the slider surface is cleaned according to the cleaning function selected by the user using the slider surface topography.

[0108] In step S518, after the work is completed, the slider shape returns to the initial state.

[0109] In step S519, it is determined whether the magnetic head arm flies smoothly. If so, the cleaning is terminated; otherwise, step S514 is continued.

[0110] In summary, the technical effects brought about by the embodiments of the present invention are as follows:

[0111] 1. By monitoring the environmental parameters inside the mechanical hard disk, the surface morphology of the slider can be adjusted, and the flight status protection of the hard disk head arm can be realized more timely, accurately and predictably, thus ensuring the normal operation of the hard disk.

[0112] 2. By collecting historical environmental parameters and predicting the changing patterns of environmental parameters in the future, we can obtain the corresponding deformation variables of each unit on the slider surface, implement a predictable control method, ensure the normal operation of the hard disk, and reduce performance impact and the risk of hard disk damage and data loss.

[0113] 3. The stable flight state of the head arm is effectively guaranteed, so that the flying height of the head can be further reduced, and the storage density of the hard disk surface is further increased, thereby reducing the cost of the hard disk.

[0114] 4. Improve the hard disk's adaptability to the environment, thereby broadening the hard disk's working environment and adapting to more extreme working conditions.

[0115] 5. Reducing environmental requirements can also reduce the construction and maintenance costs of server rooms.

[0116] According to an embodiment of the present invention, a deformation adjustment method for a deformable slider in a mechanical hard disk is proposed. When the mechanical hard disk is in operation, environmental data within the mechanical hard disk is collected and a pressure distribution of the deformable slider is determined based on the environmental data. When the deformable slider is determined to be in an underpressure or overpressure state based on the pressure distribution of the deformable slider, a deformation compensation amount of the deformable slider is determined based on the pressure distribution of the deformable slider. If the deformation compensation amount is within a preset deformation amount range, at least one driver is used to control the deformable slider to deform according to the deformation compensation amount. This solves the problem that the existing mechanical hard disk head slider structure is fixed, unable to adapt to a wide range of environments, and may not maintain stability in complex environments, resulting in abnormal performance or hard disk damage, and high control costs. The hard disk can be applied to a wider range of environmental scenarios and adapt to more complex and changing operating environments. It actively and controllably ensures normal operation. Under abnormal environmental influences, the head arm can achieve stable flight through self-adjustment, providing early warning of potential hard disk failures caused by environmental changes. The special morphology structure can collect and clean dust and particles inside the hard disk, preventing accumulation and damage to the head and disk.
