Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0038] The following combination Figure 1 The optical disc structure 10 of the present application is described.

[0039] Reference Figure 1 The optical disc structure 10 includes a silicon carbide disc 1 , a first side of which is formed with a plurality of grooves 11 , which are arranged in a spiral manner from the center to the periphery of the silicon carbide disc 1 .

[0040] In an embodiment of the present invention, silicon carbide (SiC) is a high-performance semiconductor material with excellent properties such as high hardness, high wear resistance, and high thermal conductivity. Using a silicon carbide disk 1 in a data storage medium can utilize its high thermal conductivity to effectively conduct away the heat generated during the reading and writing process, thereby reducing the operating temperature of the medium. This means that when using this silicon carbide disk 1, data centers may no longer need additional cooling systems to reduce the temperature of the storage medium, reducing data center operating costs and energy consumption. The high hardness and high wear resistance of silicon carbide give this optical disc structure 10 excellent durability and stability, meaning that data can remain intact and accessible for a longer period of time, reducing the risk of data loss or damage. Furthermore, the spiral arrangement of the grooves 11 can improve data storage density and reading efficiency. When reading data, the laser beam can move quickly along the spiral trajectory, reducing seek time and thus accelerating data reading speed. The difference in laser reflection between the grooves 11 and the flat portion enables the laser receiver to accurately detect the data signal.

[0041] The following reference Figures 2 to 5 The optical disc burner 100 of the present application is described.

[0042] Reference Figures 2 to 4According to a second aspect of the present disclosure, an optical disc burner 100 is provided. The optical disc burner 100 is used to burn an optical disc structure 10 as described above. The optical disc burner 100 includes a base 20, a mounting portion 301, a drive assembly and a burning assembly 40. The mounting portion 301 is mounted on the base 20 so as to rotate about a first axis. The mounting portion 301 is used to mount the disc-shaped silicon carbide 200. The first axis is used to be arranged colinearly with the axis of the disc-shaped silicon carbide 200. The drive assembly is mounted on the base 20 to drive the mounting portion 301 to rotate. The engraving assembly 40 is mounted on the base 20 to emit a laser to engrave multiple grooves 11 on the disc-shaped silicon carbide 200 to form a silicon carbide disk 1. In this way, when the drive assembly drives the mounting portion 301 to rotate, the disc-shaped silicon carbide 200 can rotate synchronously with the mounting portion 301 about the first axis, ensuring that the laser can accurately engrave multiple grooves 11 arranged in a spiral manner from the center to the periphery of the silicon carbide disk 1 on the disc-shaped silicon carbide 200 in a predetermined manner. This engraving method not only improves space utilization, but also allows the position of each groove 11 to be precisely controlled. The spiral layout allows the laser to move continuously and smoothly during the engraving process, thereby improving engraving efficiency. In addition, silicon carbide has high hardness and high wear resistance. By burning the grooves 11 on the disc-shaped silicon carbide 200, the data can maintain integrity and readability for a long time. The multiple grooves 11 arranged in a spiral shape improve the density of data storage and reading efficiency. Silicon carbide material has high thermal conductivity and can quickly conduct away the heat generated during the laser burning process. This reduces the cooling needs of the data center, reducing energy consumption and operating costs. The physical properties of the disc-shaped silicon carbide 200 make the burned silicon carbide disk 1 difficult to copy or tamper with, improving data security.

[0043] It should be noted that during the burning process, data is converted into a binary signal through a specific encoding method. The laser beam is then controlled to generate high temperatures on the surface of the disc-shaped silicon carbide 200 on the silicon carbide disk 1 according to a predetermined pattern, causing the disc-shaped silicon carbide 200 to partially melt, vaporize, or undergo a chemical reaction, thereby forming grooves 11. These grooves 11 are arranged in a spiral or other predetermined pattern to store data. Each groove 11 is burned according to a predetermined path and depth, thus ensuring the consistency of the burning quality. When reading data, the laser beam scans the groove 11 structure on the silicon carbide disk 1 and restores the binary signal by detecting changes in the intensity of the reflected light, thereby recovering the original data.

[0044] Reference Figure 2 and Figure 3In one embodiment, a through-hole 210 is provided in the center of the disc-shaped silicon carbide 200 along its axial direction. The mounting portion 301 includes an air-bearing spindle 31, which is rotatably mounted on the base 20 about its axis. The axis of the air-bearing spindle 31 is collinear with the first axis. The air-bearing spindle 31 is configured to allow the disc-shaped silicon carbide 200 to be mounted through the through-hole 210, so that the disc-shaped silicon carbide 200 and the air-bearing spindle 31 rotate synchronously. Thus, the disc-shaped silicon carbide 200 is mounted on the air-bearing spindle 31 through the through-hole 210. This mounting method ensures a tight connection between the disc-shaped silicon carbide 200 and the air-bearing spindle 31. When the air-bearing spindle 31 rotates about its axis, the disc-shaped silicon carbide 200 can rotate synchronously with it, eliminating the need for an additional transmission mechanism and simplifying the structure of the optical disc burner 100. The air bearing spindle 31 typically rotates with high precision and stability, which helps ensure smooth and accurate rotation of the disc-shaped silicon carbide 200. The disc-shaped silicon carbide 200 is mounted on the air bearing spindle 31 via the through-hole 210, making installation and removal simple and quick. This helps improve work efficiency and facilitates replacement or maintenance of the disc-shaped silicon carbide 200.

[0045] It should be noted that the air-floating spindle 31 is mounted on the base 20 via the air-floating bearing 32. Specifically, within the air-floating bearing 32, a high-pressure gas (typically compressed air) is introduced into the air cavity of the air-floating bearing 32 via an air supply system. Upon entering the air cavity of the air-floating bearing 32, the high-pressure gas, through the action of the airflow, forms an air film on the surface of the air-floating spindle 31. This air film plays a key role in lubrication and suspension. The formation of the air film creates an air cushion between the gas and the air-floating spindle 31, causing the air-floating spindle 31 to float under the action of the air film. This suspended state not only reduces direct contact between the air-floating spindle 31 and the air-floating bearing 32, but also reduces friction and wear. The supporting force of the air film can bear the weight and force of the air-floating spindle 31, achieving separation and stable support between the air-floating spindle 31 and the air-floating bearing 32. The air film in the air-floating bearing 32 not only provides support but also serves as a cooling and lubricating function. Through the flow of the air film, the heat on the surface of the air bearing 32 can be taken away, and the air bearing 32 can be cooled. In addition, the air bearing spindle 31 can achieve smooth operation during high-speed rotation, reducing vibration and noise. The air bearing spindle 31 is mounted on the base 20 through the air bearing 32, which can achieve high-precision rotational motion. At the same time, due to the reduction of friction and wear, the operating efficiency of the air bearing spindle 31 is also significantly improved. Compared with traditional liquid-lubricated bearings, the air bearing 32 does not require the use of a lubricating medium (such as oil or grease). This not only simplifies the structure of the optical disc burner 100, but also reduces maintenance costs. The air bearing 32 reduces the direct contact between the air bearing spindle 31 and the air bearing 32 by forming an air film, thereby extending the service life of the air bearing spindle 31 and the air bearing 32.

[0046] Reference Figure 5 A threaded channel 311 is formed inside the air-floating main shaft 31, which is wound along the first axis. The threaded channel 311 is used for gas to pass through, so that the air-floating main shaft 31 is suitable for being driven to rotate. In this way, the threaded channel 311 is wound along the axial direction inside the air-floating main shaft 31. This design allows the gas to form a specific flow path inside the air-floating main shaft 31. When an external gas source supplies gas to the threaded channel 311, when the gas flows in the threaded channel 311, due to the guidance of the thread shape, the gas will generate a certain tangential force on the air-floating main shaft 31. This tangential force is the source of power that drives the main shaft to rotate. When the gas flow rate is large enough, this tangential force can overcome the rotational resistance of the main shaft, causing the main shaft to start rotating. The design of the threaded channel 311 further enhances the stability of the air-floating main shaft 31, so that it can still maintain high precision when rotating at high speed.

[0047] Reference Figures 2 to 4 In one embodiment, the writing assembly 40 includes a laser head 401 and a focusing unit 402. The laser head 401 is mounted on the base 20 for movement radially relative to the air bearing spindle 31. The laser head 401 is configured to emit laser light, and the focusing unit 402 is positioned corresponding to the laser head 401. The focusing unit 402 is used to focus the laser light directed toward the disk-shaped silicon carbide 200, ensuring that the laser beam impinges on the disk-shaped silicon carbide 200 with a very small diameter, thereby achieving high-precision data writing. The focusing unit 402 is used to focus the laser light reflected from the silicon carbide disk 1, ensuring that the laser beam is reflected with a very small diameter, facilitating subsequent accurate data reading. The laser head 401 is mounted on the base 20 in a radially movable manner along the air-floating spindle 31. This mounting method enables the laser head 401 to scan the disc-shaped silicon carbide 200 from the center to the edge of the disc-shaped silicon carbide 200, so as to ensure that the laser head 401 can be accurately moved to the target position for burning. In addition, the radially movable mounting of the laser head 401 enables it to move quickly on the disc-shaped silicon carbide 200, thereby improving the reading and writing speed.

[0048] It should be noted that in some embodiments, by adjusting the parameters of the focusing unit 402, the diameter and focus depth of the laser beam can be controlled, thereby ensuring that the laser can accurately irradiate the surface of the disk-shaped silicon carbide 200. The focusing unit 402 may include a lens or other optical elements that can change the propagation path and focusing characteristics of the laser. Depending on the laser power and irradiation time, tiny pits or protrusions can be formed on the silicon carbide surface, representing data information.

[0049] Reference Figures 2 to 4In one embodiment, an air-bearing spindle 31 is used to accommodate multiple disc-shaped silicon carbide (SiC) disks 200. These disks are spaced apart along the axial direction of the spindle 31. Multiple stoppers 50 are removably mounted on the spindle 31 to restrict the axial movement of the SiC disks 200. This allows for high-precision, frictionless support of the spindle 31, thanks to the air film formed by the flow of gas within the spindle. This support method not only improves the rotational accuracy and stability of the spindle 31, but also reduces friction and wear, extending its service life. The multiple SiC disks 200, spaced apart along the axial direction of the spindle 31, form a data storage medium. Each SiC disk 200 can independently store data, and data can be recorded on the multiple SiC disks 200 through the rotation of the spindle and the coordination of the laser head 401. By detachably attaching multiple limiting portions 50 to the air-bearing spindle 31, the limiting portions 50 can be removed from the air-bearing spindle 31 when multiple disc-shaped silicon carbides 200 need to be installed. After the multiple disc-shaped silicon carbides 200 are installed, the limiting portions 50 are attached to the air-bearing spindle 31 to restrict the axial movement of the multiple disc-shaped silicon carbides 200 along the air-bearing spindle 31, thereby preventing the multiple disc-shaped silicon carbides 200 from shifting or falling off during the rotation of the air-bearing spindle 31. In addition, the detachable design of the limiting portions 50 allows users to easily install or remove the disc-shaped silicon carbides 200 and adjust the spacing between them. This design improves the flexibility and ease of use of the optical disc burner 100, allowing users to configure the data storage capacity and layout according to actual needs.

[0050] It should be noted that there are many types of limiting portions 50. For example, in one embodiment, the sidewall of the air-floating spindle 31 may be provided with multiple slots, and the limiting portion 50 is configured as a clamping platform that matches the slots. The multiple clamping platforms are respectively clamped into the multiple slots, and along the axial direction of the air-floating spindle 31, the clamping platforms are used to abut against the end face of the disc-shaped silicon carbide 200. In other embodiments, the limiting portion 50 may also include a clamping hoop that is tightly clamped to the air-floating spindle 31, and along the axial direction of the air-floating spindle 31, the clamping hoop abuts against the end face of the disc-shaped silicon carbide 200. In other embodiments, the limiting portion 50 may also include a clamp, a strap, etc. Specifically, this application does not limit the specific type of limiting portion 50. The limiting portion 50 is generally designed to have a shape that matches the outer edge or specific portion of the disc-shaped silicon carbide 200 to ensure that they can tightly fit and fix the disc-shaped silicon carbide 200.

[0051] Reference Figures 2 to 4In one embodiment, a plurality of burning components 40 are provided, and the plurality of burning components 40 are used to correspond to the plurality of disk-shaped silicon carbide 200, so that each burning component 40 is suitable for burning the corresponding disk-shaped silicon carbide 200. In this way, the plurality of burning components 40 process in parallel, and each burning component 40 is capable of performing a burning operation on a specified disk-shaped silicon carbide 200, which greatly improves the overall burning speed and shortens the data processing time.

[0052] Reference Figure 2 exist Figure 4 In one embodiment, the optical disc burner 100 further includes a photoelectric converter 60, which is mounted on the base 20. The photoelectric converter 60 is capable of converting the laser light reflected from the silicon carbide disc 1 and focused by the focusing portion 402 into an electrical signal. In this way, the photoelectric converter 60 converts the weak reflected light signal into a clear electrical signal, thereby improving the accuracy and reliability of data reading.

[0053] Specifically, the principle of reading silicon carbide disk 1 is as follows: When laser head 401 emits a laser beam, this laser beam is focused by focusing unit 402 and accurately irradiated onto the surface of silicon carbide disk 1. If the surface of silicon carbide disk 1 is smooth, the laser beam will be focused by focusing unit 402 and reflected back to laser head 401. It is received by photoelectric converter 60. Photoelectric converter 60 uses the photoelectric effect to convert the reflected laser beam into an electrical signal. The converted electrical signal undergoes further processing, such as amplification and filtering, and is ultimately used to read data or control further laser scribing. If the surface of silicon carbide disk 1 is grooved or uneven, the light will be refracted, preventing the reflected light from being focused on photoelectric converter 60 to form an electrical signal.

[0054] Reference Figure 2 exist Figure 4In one embodiment, the optical disc burner 100 further includes a digitizer 70 mounted on the base 20. The digitizer 70 converts the electrical signal output by the photoelectric converter 60 into a digital signal. To do this, the photoelectric converter 60 first focuses the laser light reflected from the optical disc through the focusing unit 402 and then converts it into an electrical signal. These electrical signals are typically analog signals, with amplitude and frequency corresponding to the intensity and fluctuations of the laser light. The digitizer 70 converts the analog signals into digital signals through a sampling and quantization process. After sampling and quantization, the digital signals output by the digitizer 70 can be further processed and analyzed by a subsequent data processing system. These digital signals are typically used for operations such as data reading, error detection and correction, and controlling further scribing by the laser head 401. The digitizer 70 accurately converts analog signals into digital signals, thereby reducing distortion and errors during signal transmission and processing. This helps improve the accuracy and reliability of data reading. Digital signals offer greater flexibility and scalability. Through the digitizer 70, the optical disc burner 100 can easily connect and communicate with various digital devices and systems, enabling rapid data transmission and sharing. The digital signal output by digitizer 70 can be used for various advanced data processing operations, such as data encryption, compression, and decompression. These operations help protect data privacy and security while improving data storage and transmission efficiency. By accurately converting analog signals into digital signals, digitizer 70 helps reduce noise and interference, thereby ensuring that the optical disc burner 100 can operate continuously and stably.

[0055] It should be noted that sampling refers to taking values from an analog signal at regular intervals, thereby obtaining a series of discrete signal values; quantization involves mapping each sampled value to the nearest digital value, thereby obtaining a series of discrete digital signals. Furthermore, the electrical signal output from the photoelectric converter 60 typically undergoes processing via an amplifier and a filter before entering the digitizer 70. The amplifier increases the signal's amplitude, making it easier for the digitizer 70 to recognize; the filter removes noise and interference from the signal, improving its purity.

[0056] Reference Figure 2 exist Figure 4In one embodiment, the optical disc burner 100 further includes a data buffer 80, which is mounted on the base 20. The data buffer 80 is capable of temporarily storing data to be written to the disc-shaped silicon carbide 200 or data to be read from the silicon carbide disk 1. In this manner, the data buffer 80 temporarily stores the received data in an internal storage medium. For data to be written to the disc-shaped silicon carbide 200, the data buffer 80 gradually writes the data to the silicon carbide disk 1 based on the write speed of the optical disc burner 100 and the format requirements of the silicon carbide disk 1. For data to be read from the silicon carbide disk 1, the data buffer 80 pre-reads a portion of the data and stores it internally to quickly respond to data requests from the computer system. Furthermore, the data buffer 80 can smoothly adjust the data transmission speed to accommodate the write speed of the optical disc burner 100. This helps reduce waiting time during data transmission and improves data writing efficiency. The data buffer 80 can act as a buffer, reducing system instability caused by data transmission speed mismatch. For example, when a computer system needs to write a large amount of data to the optical disc burner 100, the data buffer 80 can receive the data in batches and then gradually write it to the silicon carbide disk 1, thereby avoiding congestion and conflicts during the data transmission process. The data buffer 80 helps prevent cache underrun errors. A cache underrun occurs when the data transmission speed is lower than the burning speed, causing the data in the data buffer 80 to be depleted, resulting in an interruption in the burning process. The data buffer 80 can store sufficient data to cope with this speed mismatch, thereby ensuring a smooth burning process and improving the burning quality. The data buffer 80 allows the optical disc burner 100 to process multiple data requests simultaneously. For example, when reading data, the data buffer 80 can store data requests from multiple applications and respond to them one by one according to priority and reading speed. This helps improve the overall performance and responsiveness of the system. During the data transmission process, if there is an unexpected interruption (such as a power failure or system crash), the data in the data buffer 80 can still be saved. This helps reduce the risk of data loss caused by data transmission interruptions.

[0057] In one embodiment, the optical disc burner 100 further includes a controller electrically connected to the burning component 40, the digitizer 70, the data buffer 80, and the drive component. Thus, the controller precisely controls the entire burning process by sending control signals and receiving status feedback. The controller receives data write or read requests from the computer system and processes these requests. During processing, the controller determines the optimal write or read strategy based on information such as the data type, size, and format. The controller coordinates operations between the burning component 40, the digitizer 70, the data buffer 80, and the drive component by sending control signals to them. For example, when writing data, the controller controls the laser head 401 to irradiate the surface of the disc-shaped silicon carbide 200 at an appropriate power and speed, while simultaneously adjusting the drive component to drive the mounting portion 301 to rotate at an appropriate speed so that the disc-shaped silicon carbide 200 can rotate synchronously and stably with the mounting portion 301. By precisely controlling the recording component 40, digitizer 70, data buffer 80, and drive assembly, the recording process of the disc-shaped silicon carbide 200 can be optimized, increasing both data writing and reading speeds. This helps reduce recording time and improves the overall efficiency of the optical disc recorder 100. The controller can simultaneously process multiple data requests, enabling multitasking and parallel processing. This helps improve system responsiveness and overall performance.

[0058] It should be noted that the controller is also responsible for monitoring the operating status of various components, such as the position, power, and focal length of the laser head 401, the storage status of the data buffer 80, and the rotational speed of the drive components. By receiving this status information, the controller can promptly adjust the control strategy to ensure a smooth burning process. During the burning process, the controller detects possible errors such as data loss, write errors, or read errors. If an error is detected, the controller immediately takes corrective measures, such as rewriting the data or reading data from another location, to ensure data integrity and accuracy.

The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present invention.
