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 combined with the structure of the original optical disc by interlayer production. In this way, 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. , but it cannot protect the disc from scratches during the data writing process, so it will also cause the probability of disc data writing errors

Embodiment 1

[0021] In the overall injection, it contains 60% of acrylate resin, 32% of TMPA and its EO.PO modified monomer, 5% of Irgacure-184 sensitizer, and 3% of wax to form a 40-50cps / 25° Viscosity state, under the working condition of the surface temperature of the optical disc at 35°C, apply the injection agent to the surface layer of the data reading and writing surface of the optical disc by means of centrifugal coating, and after the injection agent is coated, it takes 5 seconds to match The injection is irradiated with ultraviolet rays, so that the ingredients in the injection are converted into a light-transmitting film with a film thickness of 0.01±0.002mm with a hardness between 2H-7H, so that the light-transmitting film forms an optical disc The anti-scratch surface of the disc, in order 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 flat, so as to increase the service life of...

Embodiment 2

[0023] The overall injection contains 60% acrylate resin, 24.5% monomer, 12.5% ​​Irgacure-184 sensitizer, and 3% wax to form a viscosity state of 40-50cps / 25°. Under the working condition of 47°C, the injection agent is applied to the surface layer of the data reading and writing surface of the optical disc by means of centrifugal coating, and after the injection agent is coated, the injection agent is irradiated with ultraviolet light for 2.5 seconds.

Embodiment 3

[0025] In the overall injection, it contains 60% acrylate resin, 17% TMPA and its EO.PO modified monomer, 20% Irgacure-184 sensitizer, and 3% silane at 40-50cps / 25° In the viscosity state of the optical disc, under the working condition of the surface temperature of the optical disc at 60°C, apply the injection agent to the surface layer of the data reading and writing surface of the optical disc by means of centrifugal coating, and after the injection agent is coated, within 1 second The injection is irradiated with ultraviolet rays.

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 the data on the disc position, so the data reading and writing layer of the general optical disc especially needs to maintain a considerable level of flatness to avoid the impact of reading and writing due to scratches The laser light irradiation of the head, thereby reducing the accuracy of the ove...
