Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 In the device for depositing a diamond-like film on the surface of a dielectric barrier discharge plasma optical disc, the discharge plasma chamber (1) is a vacuum sealed chamber. The AC sine wave high voltage (2) used to generate plasma is connected to the high voltage electrode (3), and the plasma (5) is generated on the gas gap between the high voltage electrode and the ground electrode (4) after high voltage discharge. The size of the gas gap is adjustable between 1-10mm. The clean disc (6) is placed on the ground electrode as a deposition base, and active species generated by the plasma are deposited on the surface of the disc to form a diamond-like film. The glass medium (7) acts as an insulating medium for generating dielectric barrier discharge. Discharge gas such as Ar, CH 4 、C 2 h 4 etc. enter by air inle...

Abstract

The invention relates to a method for coating a film on the surface of a compact disc and a method for depositing an acid-resistant and alkaline-resistant diamond film on the surface of the compact disc. The method comprises the steps of using a low and medium frequency medium to baffle high voltage discharge; using micromolecule hydrocarbon gas; and under the condition of lower air pressure, using the compact disc as a depositing substrate to deposit an ultrahard diamond film on the surface of the compact disc. The invention uses the medium to baffle discharge plasma to deposit the film, has the following unique advantages: simple discharge mode, low power energy and low gas flow, and can realize deposition on an insulating medium. The film has permeability which is more than 90% in blue light and red light for CD-ROM work recording and reading laser wave length. By testing the coated compact disc in a way of recording and reading, the film is proved to have no effect to the normal work of the compact disc. The invention effectively improves the chemical stability and the mechanical property of the surface of the compact disc, therefore, the coated compact disc has good acid-resistant and alkaline-resistant property.

Description

Technical field: [0001] The invention relates to a method for coating the surface of an optical disk, in particular to a method for depositing a diamond-like film on the surface of an optical disk, and also relates to a coating device. Background technique: [0002] Compact Disc (Compact Disc) is an optical storage medium developed in modern times that is different from magnetic carriers. It uses a focused hydrogen ion laser beam to process the recording medium to store and reproduce information, also known as laser disc. The development of CD-ROM and the invention of paper have greatly promoted the progress of human civilization. It records the development history of human civilization and created a number of emerging industries. The disc substrate material is aromatic polycarbonate, and its molecular chemical structure is: Its structure contains aromatic rings and carboxyl groups, and it does not have acid and alkali resistance. Because it is a typical polymeric organic...
