Problems solved by technology

[0003] However, the anti-scratch treatment of ordinary optical discs is mostly carried out after the optical disc data is manufactured. In order not to affect the properties of the optical disc data layer, the anti-scratch structure is mostly made of an interlayer to match the structure of the original optical disc. In combination, not only the processing process is cumbersome, but also the relative overall production cost of the optical disc is also increased, so as to reduce its competitiveness in the market; especially, the conventional scratch-resistant layer structure is formed after the optical disc data is manufactured. However, it cannot protect the disc from scratches during the data writing process, so it will also cause the possibility of disc data writing errors

Embodiment 1

[0024] In the overall injection, it contains 60% of acrylate resin, 32% of trimethylolpropane triacrylate (TMPTA) and its EO.PO modified monomer, 5% of Irgacure-184 photosensitizer, and 3% of The wax is in a viscosity state of 40-50cps / 25°. Under the working condition of the surface temperature of the optical disc at 35°C, the injection is applied to the surface of the data reading and writing surface of the optical disc by means of centrifugal coating, and the injection is confirmed. After coating, irradiate the injection with ultraviolet light for 5 seconds, so that the ingredients in the injection can be converted into a light-transmitting film with a film thickness of 0.01±0.002mm with a hardness between 2H-7H , the anti-scratch surface of the optical disc is formed by the light-transmitting film, so as to form an effective anti-scratch effect on the data reading and writing surface of the optical disc, and keep the data reading and writing surface smooth, so as to increase...

Abstract

The invention discloses a manufacturing method for scrapping-resistant surface of reading and writing disk. It is coated with the infusing agent which is made up of resin, monomer, sensitizer and assistant with proper proportion on the data reading and writing surface of the disk by acentric pasting method, after the infusing agent is pasted, irradiate the infusing agent with ultraviolet in order to transform the ingredients in agent into a transparent film with proper rigidity. The film does not affect the reading of data on disk, and the film can form an anti-scratching effect to the surface, maintains the flat of the surface and increase the life of the disk.

Description

technical field [0001] The invention relates to a method for manufacturing a scratch-resistant read-write surface of a read-write optical disc, in particular to a method for effectively and reliably forming a scratch-resistant translucent film on the data read-write surface of an optical disc method. Background technique [0002] Press, in the data reading process of a general optical disc, it mainly uses the read-write head to read the data according to the state of the laser light reflected after it is projected onto the data layer of the optical disc, so the laser light is projected and The travel route during the receiving process will directly affect the accuracy of reading data on the disc position, so the data reading and writing layer of general optical discs must be kept fairly flat to avoid scratches that affect reading and writing The laser light irradiation of the head, thereby reducing the accuracy of the overall data reading and writing. [0003] However, the...
