Abstract
An anti-scratch optical disk with diamond film is made up through activating the carbon atoms in carbon containing hydrocarbons by high-frequency electric field in vacuum condition to make SP3 bonds be hybridized and combined to form diamond film with right pyramid structure, which is attached on the surface of optical disk. It can resist againt scratch as the diamond film has high hardness and finish degree and low friction coefficient.
Description
The present invention relates to a kind of anti-scratch, diamond film CD and production method thereof
CD is the important information record storage carrier in modern computer field, makes protective seam but adopt poly-carbon ester plastics because of its surface.This layer plastics hardness is relatively poor, easily scratches, and damages, and causes image and information demonstration mistake or whole adjustment debit bad, influences the permanent preservation of data message.
The present invention seeks to add the diamond film of attached layer of transparent diamond crystal structures, improve optical disc surface hardness and luminance brightness, improve the ability of optical disc surface scratch resistance rub resistance at optical disc surface.
Purpose of the present invention realize be with CD under vacuum condition, utilize the effect of high-frequency electric field to activate carbon atom in the carbonaceous material, make carbon atom be arranged as the positive tetrahedron crystal structure continuously and form stable diamond crystal film and produce diamond film CD by the SP3 hybrid bond.
Concrete operations are as follows:
CD-→ loading electrode-→ reaction chamber-→ film forming-→ diamond film CD
With CD pack that multipole plate electrode accompanying drawing shows 1 into, electrode puts into the vacuum chamber accompanying drawing and shows 2, is evacuated to 5Pa and adds carbonaceous material (hydro carbons) accompanying drawing and show 3, add high frequency power source 13 megahertzes, voltage 1300V electric current 0.1A is to diamond crystal film thickness 0.5-1 μ m.
The diamond film CD parameter:
Thickness 1.2mm
Diameter external diameter 120mm internal diameter 15mm
Free Region 44.7～118mm
The trade shape spiral
Orbit altitude 16 μ m
Capacity 74 minutes or 650 megabyte
Skin hardness 2000～6000kg/mm
2
Friction factor 0.01～0.02
