Description

광디스크의 구조Structure of optical disc

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 대한 것으로 (가)는 단면을 보인 사시도. (나)는 요부확대 정 단면도.1 is a perspective view showing a cross-sectional view (a) of the present invention. (B) Sectional enlargement of the main part.

제2도는 시간에 따른 광디스크 기록막의 광투과율 변화그래프로서 그래프 1은 Te 단일기록막의 시간에 따른 광투과율 변화 그래프 2는 본 발명에 따른 산화방지막이 형성된 기록막의 시간에 따른 광투과율의 변화.2 is a graph of the light transmittance of the optical disc recording film with time. FIG. 1 is a graph of the light transmittance with time of the Te single recording film.

제3도는 광디스크의 C/N비 (Carrier to noise Ratio)측정장치의 계통도.3 is a schematic diagram of an apparatus for measuring carrier to noise ratio of an optical disc.

Claims (2)

에너지빔의 조사에 의한 기록막의 물리적변형 형태가 요입홈이나 구멍형태로 이루어지는 통상의 에어샌드위치형 광디스크 구조에 있어서 기판과 Te기록막 사이에 SiOx(1〈x〈2)로 이루어지는 산화방지막을 형성시킨 것을 특징으로 하는 광디스크 구조.In a conventional air-sandwich type optical disc structure in which the physical deformation of the recording film by energy beam irradiation is in the form of recesses or holes, an oxide film made of SiOx (1 <x <2) is formed between the substrate and the Te recording film. An optical disk structure, characterized in that. 제 1 항에 있어서, Te기록막은 200-600Å 두께로 형성되고 산화방지막은 50-100Å으로 형성된 것을 특징으로 하는 광디스크의 구조.2. The structure of an optical disc according to claim 1, wherein the Te recording film is formed in a thickness of 200-600 mW and the antioxidant film is formed in 50-100 mW. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
