Description

Technical Field

[0001] This application belongs to the field of optical storage technology, and in particular relates to a glass optical disc based on explosion-proof and anti-adhesion properties and its manufacturing method. Background Technology

[0002] Glass-based multidimensional optical storage technology, represented by fused silica, has shown broad application prospects in the field of big data archiving and storage due to its advantages such as large storage capacity and data lifetime of up to tens of thousands of years. Glass materials have excellent chemical stability and optical properties, and can be used to fabricate micro- and nano-structures in three-dimensional space using femtosecond lasers to achieve high-density, permanent data storage.

[0003] However, glass, as a typical hard and brittle material, inherently possesses brittleness during processing and use, making it prone to breakage. This is especially true for optical discs with a central hole structure, where stress concentration during frequent clamping with optical drive calipers makes this area a weak point in the structure. Furthermore, during long-term stacking and storage of optical discs, intermolecular forces can easily form on their surfaces under the influence of pressure and temperature / humidity changes, causing the discs to stick together. This can not only damage the disc surface but also cause inconvenience for data access.

[0004] Existing optical disc protection solutions mostly focus on surface cleaning or simple reinforcement, lacking specialized explosion-proof designs for core stress areas (such as the center hole), and also failing to effectively solve the sticking problem caused by long-term stacking. Current technologies cannot simultaneously achieve shock protection for critical areas and physical isolation during stacking, exhibiting significant shortcomings in ensuring data storage reliability and ease of use, and suffering from poor anti-sticking properties and a tendency to crack. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art.

This method, by attaching an explosion-proof film to the surface of the disc's central hole, reduces adhesion when discs are stacked, provides a protective buffer for the central hole during disc clamping, reduces edge breakage of the central hole, improves the disc's stability, reduces contamination of the optical drive's internal precision optical components by tiny debris generated from internal hole breakage, and extends the optical drive's lifespan. It effectively reduces the risk of breakage and adhesion during daily use and storage of glass optical discs, improves data storage reliability, reduces maintenance risks, improves management efficiency, and extends disc lifespan.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0021] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0022] The glass optical disc design method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0023] As the core carrier of data, the optical disc itself is made of high-purity quartz glass or aluminosilicate glass, which has extremely high Vickers hardness and excellent optical transmittance. Although the glass material has high hardness, it has low fracture toughness and high Young's modulus. When the spindle jaws of a traditional optical disc drive are opened for clamping, the hard contact between the metal jaws and the center hole of the glass can easily cause micro-cracks at the edges, which can lead to catastrophic breakage.

[0024] Figure 1 This is one of the structural schematic diagrams of a glass optical disc based on explosion-proof and anti-adhesion provided in the embodiments of this application, such as... Figure 1 As shown, the glass optical disc includes an optical disc body 1, which has a central hole. The optical disc body 1 includes a data recording area and an explosion-proof film 2. The explosion-proof film 2 is used to wrap a first annular area on the upper surface of the optical disc body 1, the inner surface of the central hole of the optical disc body 1, and the lower surface of the optical disc body 1. The inner diameter of the first annular area is equal to the radius of the central hole. The explosion-proof film 2 is a high-molecular PET film, and the light transmittance of the explosion-proof film 2 is greater than or equal to 90%.

[0025] For example, the inner surface of the explosion-proof film 2 is fixed to the first annular area on the upper surface of the optical disc body 1, the inner surface of the central hole of the optical disc body 1, and the lower surface of the optical disc body 1 by optical adhesive or pressure-sensitive adhesive.

[0026] Optionally, the explosion-proof membrane 2 is made of high-molecular-weight polyethylene terephthalate material with good tensile strength and elastic recovery. When radial pressure is applied, the explosion-proof membrane 2 undergoes a slight elastic deformation, transforming the concentrated point load applied by the claws into a distributed surface load, effectively dissipating mechanical stress, thus playing a crucial protective and buffering role for the edge of the glass central hole and preventing breakage caused by stress concentration.

[0027] In some embodiments, the lower surface of the optical disc body 1 includes a second annular region, the inner and outer diameters of the second annular region being the same as the inner and outer diameters of the first annular region; The explosion-proof film 2 in the first and second annular regions is configured as an anti-adhesion structure. The anti-adhesion structure is a micro-bump array, a frosted rough surface, or a spiral texture structure, which is used to create air gaps when the optical discs are stacked. The anti-adhesion structure is printed with an identification mark, which includes a random code or a QR code, for tracing and managing the optical disc body 1.

[0028] In some embodiments, the lower surface of the optical disc body 1 further includes a third annular region, the inner and outer diameters of the third annular region being the same as the inner and outer diameters of the second annular region, the explosion-proof film 2 at the first annular region having the same thickness as the explosion-proof film 2 at the second annular region, and the thickness of the explosion-proof film 2 at the second annular region being greater than the thickness of the explosion-proof film 2 at the third annular region.

[0029] For example, the explosion-proof film 2 has a thickness of 0.2-0.3 mm in the first and second annular regions to prevent the optical disc bodies 1 from sticking together when stacked. This thickness provides sufficient mechanical damping to effectively absorb the minor vibrations during high-speed rotation of the optical disc, improving reading stability. This thickness physically elevates the central region, naturally creating a small air gap between the data areas of the upper and lower optical discs when stacked, thus physically preventing direct contact and wear between the data surfaces. During the clamping process of the optical disc body 1, it protects and buffers the central hole, preventing the edge of the central hole from breaking. The explosion-proof film 2 has a thickness of 0.1 mm in the third annular region.

[0030] In this embodiment, by introducing an explosion-proof film, the traditional metal-glass hard contact is successfully transformed into a metal-polymer film-glass soft contact, thereby improving the explosion-proof and anti-stick properties of the glass optical disc.

[0031] In some embodiments, the ring width of the first annular region is 14%-17% of the ring width of the optical disc body 1.

[0032] In some embodiments, the glass optical disc further includes a hard coating layer located on the outer surface of the explosion-proof film 2, which is used to improve the scratch resistance of the optical disc body 1.

[0033] For example, Figure 2 This is a side view of the glass optical disc based on explosion-proof and anti-adhesion provided in the embodiments of this application, as shown below. Figure 2 As shown, a polymer explosion-proof film 2 is adhered and covered to the entire inner surface of the optical disc body using an adhesive bonding process. The lower surface of the optical disc body 1 includes an anti-adhesive area and a data recording area. Figure 2 Figure (a) shows a cross-sectional view of the explosion-proof film 2 located in the anti-adhesion area of ​​the optical disc body 1. The explosion-proof film 2 on the back of the optical disc body 1 can cover the entire lower surface of the optical disc body 1. Figure 2 Figure (b) shows that the explosion-proof film 2 is located on the lower surface of the entire optical disc body 1, covering the anti-sticking area and the data recording area. The thickness of the explosion-proof film 2 in the anti-sticking area is 0.2-0.3mm, and the thickness of the explosion-proof film 2 in the data recording area is 0.1mm. The explosion-proof film 2 in the data recording area is a transparent film, which can play a better protective role.

[0034] For example, the outer surface of the explosion-proof film 2 integrates a micro-nano scale anti-adhesion structure. When two highly flat glass optical discs are stacked, the air between the contact surfaces is easily expelled, creating an effect similar to a vacuum suction cup or generating van der Waals force adsorption, making it difficult to separate the discs. The explosion-proof film in the anti-adhesion area is a micro-bump array, a frosted rough surface, or a spiral texture structure. This is used to disrupt the continuity of the contact surfaces, changing the contact mode of the two discs when stacked from surface contact to point contact. This reduces the contact area, lowers the coefficient of friction, introduces air channels, and disrupts the vacuum adsorption conditions, making it suitable for applications of glass optical discs in scenarios such as automated robotic arm gripping and dense storage in libraries.

[0035] It is easy to understand that a micro-bump array, a frosted structure, or a spiral texture structure are made on the surface of the explosion-proof film 2 near the center hole of the optical disc body 1. For example, the height of the micro-bump array is 5μm-20μm, and the roughness of the frosted surface is 0.5μm-2μm. When the optical discs are stacked, there are a large number of air gaps on the contact surface of the explosion-proof film 2, which achieves the anti-sticking function.

[0036] It is easy to understand that, in order to reduce scratches on the surface of the optical disc by dust and other foreign objects during daily use, in some embodiments, the glass optical disc also includes a hard coating, which is located on the outer surface of the explosion-proof film and is used to improve the scratch resistance of the optical disc body 1.

[0037] In some embodiments, an identification mark is printed on the anti-adhesion structure, the identification mark including a random code or a QR code, for tracing and managing the optical disc body 1.

[0038] For example, a unique identifier for the optical disc body 1 can be printed on the frosted area of ​​the explosion-proof film 2. The unique identifier can be composed of a random, non-repeating code or a QR code, which can be identified by taking a picture with a camera.

[0039] Furthermore, the laser needs to write data into the data recording area through the upper surface of the optical disc body 1. Figure 3 This is a second schematic diagram of the structure of a glass optical disc based on explosion-proof and anti-adhesion provided in the embodiments of this application, as shown below. Figure 3 As shown, the explosion-proof film 2 should not cover the front area of ​​the data recording area so that the laser can be focused onto the interior of the optical disc body 1 without loss. Data reading typically uses a transmission microscopy optical path, therefore the explosion-proof film 2 below the data recording area should not have any surface structure, so that the explosion-proof film 2 maintains sufficiently high transparency so that a clear image can be obtained during the data reading process.

[0040] For example, after the explosion-proof film 2 is prepared, a high-resolution CCD camera automatically scans the QR code on the frosted area of ​​the center hole of the optical disc body 1. This unique identifier, along with the optical disc's metadata (such as manufacturing date and initial capacity), is uploaded to the database of the optical disc archive management system to establish a digital identity for the physical optical disc. Before data is written, the optical disc is inserted into a dedicated initialization drive. The drive first reads the QR code to verify the legality of the optical disc with the management system.

[0041] The glass disc to be archived is inserted into the archiving drive. The drive's built-in miniature camera immediately captures the QR code at the center hole of the disc body 1 and sends the identified identifier to the upper-layer application. The drive uses a transmission-type focusing servo system to precisely focus the laser beam onto the data layer inside the disc. Based on the encoded data signal, a high-power pulsed laser creates permanent micro-nano-scale structural changes within the glass material through femtosecond laser nonlinear effects, completing the data input.

[0042] When data access is required, insert the glass disc into any authorized optical drive. The drive first recognizes the QR code to confirm that the glass disc is on the authorized access list. Data is read using a transmission microscopy optical path: the reading laser beam passes through the explosion-proof film and is focused on the target data point. Due to the high light transmittance of the explosion-proof film, the sensor can receive clear transmission microscopic images or confocal signals.

[0043] Figure 4 This is a schematic flowchart of a method for manufacturing a glass optical disc based on explosion-proof and anti-adhesion provided in an embodiment of this application, as shown below. Figure 4 As shown, the method for manufacturing a glass optical disc includes steps 410, 420, 430, 440, and 450.

[0044] Step 410: Perform surface pretreatment on the glass substrate to obtain the optical disc body 1; In some embodiments, the surface pretreatment of the glass substrate to obtain the optical disc body 1 includes: The glass substrate comes in two diameters, 120mm and 150mm, with a thickness of 2mm, and center hole diameters of 20mm and 25mm. Cutting, drilling, and double-sided polishing processes have been completed.

[0045] The glass substrate was cleaned with deionized water and isopropanol in sequence, and then wiped with a lint-free cloth to obtain the optical disc body 1.

[0046] Step 420: The inner surface of the explosion-proof film 2 is attached to the first annular area on the upper surface of the optical disc body 1, the inner surface of the center hole of the optical disc body 1, and the lower surface of the optical disc body 1 by means of inner hole bonding and outer hole bonding. In some embodiments, the process of attaching the inner surface of the explosion-proof film 2 to the first annular region on the upper surface of the optical disc body 1, the inner surface of the central hole of the optical disc body 1, and the lower surface of the optical disc body 1 through inner hole bonding and outer hole bonding includes: A high-precision film applicator is used to press the explosion-proof film 2 into the center hole of the optical disc body 1, and the position of the explosion-proof film 2 is initially fixed by UV pre-curing. The explosion-proof film 2 is applied at a uniform speed, and the gas is removed by rolling with a rubber roller. It is then cured by UV light. The inner surface of the explosion-proof film 2 is then attached to the first annular area on the upper surface of the optical disc body 1, the inner surface of the center hole of the optical disc body 1, and the lower surface of the optical disc body 1.

[0047] Furthermore, a precision die-cutting machine is used to cut the explosion-proof film into a specific shape, and a high-precision laminating machine is used to press the explosion-proof film 2 into the center hole of the optical disc body 1. The position of the explosion-proof film 2 is initially fixed by UV pre-curing. The explosion-proof film 2 is then laminated at a uniform speed, and a rubber roller is used to roll and remove air. It is then cured by UV light, and the inner surface of the explosion-proof film 2 is attached to the first annular area on the upper surface of the optical disc body 1, the inner surface of the center hole of the optical disc body 1, and the lower surface of the optical disc body 1.

[0048] Step 430: Create an anti-adhesion structure on the outer surface of the explosion-proof film 2; In some embodiments, the fabrication of an anti-adhesion structure on the outer surface of the explosion-proof film 2 includes: A micro-bump array, frosted or spiral texture is created on the outer surface of the explosion-proof film 2 using an ultraviolet laser etching machine to form a rough, non-stick structure.

[0049] Step 440: Print identification markings on the non-adhesive structure; In some embodiments, printing identification marks on the anti-adhesive structure includes: A smooth area is reserved on the anti-stick structure, and an identification mark is printed using an inkjet printer and cured by UV light.

[0050] For example, a smooth area is reserved in the frosted area, and a QR code label is printed using an inkjet printer.

[0051] Step 450: Prepare a hard coating on the outer surface of the explosion-proof film 2.

[0052] For example, a UV-curable SiO2 nanocomposite coating is applied to the explosion-proof film area using a local coating technique, and after leveling, it is cured using a UV lamp.

[0053] According to the glass optical disc manufacturing method based on explosion-proof and anti-adhesion provided in the embodiments of this application, by attaching an explosion-proof film to the surface of the center hole of the optical disc, the adhesion of the optical discs can be reduced when stacking them. During the optical disc clamping process, the center hole is protected and buffered, reducing the breakage of the center hole edge, improving the stability of the optical disc, reducing the contamination of the precision optical components inside the optical drive by tiny debris generated by the breakage of the inner hole, and extending the service life of the optical drive. It can effectively reduce the risk of breakage and adhesion of glass optical discs during daily use and storage, improve data storage reliability, reduce the maintenance risk of glass optical discs, improve management efficiency and extend the life of the optical discs.
