Abstract

본 발명은 옹버 라이트시의 비트형상의 변형을 효과적으로 억제시켜 그에 따른 지터발생을 방지함과 동시에 반복기록에 따른 기록막의 유동에 의한 열화발생을 억제하도록 한 광디스크를 제공함을 목적으로 하고 있다.It is an object of the present invention to provide an optical disc which effectively suppresses bit deformation during write of an omber, thereby preventing jitter from occurring and at the same time suppressing the occurrence of deterioration due to the flow of the recording film due to repetitive recording.

이와 같은 목적을 달성하기 위한 본 발명의 광디스크는, PC 기판과, 상기 PC 기판상에 형성된 Au층과, 상기 Au층상에 적층된 제1유전체층과, 상기 제1유전체층상에 상변화형 물질로 형성된 기록막과, 상기 기록막위에 형성된 제2유전체층과, 상기 제2유전체층상에 Si 반사막과, Si 반사막에 순차로 형성된 A1 금속반사막 및 UV 수지층을 구비함을 특징으로 하고 있다.An optical disk of the present invention for achieving the above object is formed of a PC substrate, an Au layer formed on the PC substrate, a first dielectric layer laminated on the Au layer, and a phase change material on the first dielectric layer. And a recording film, a second dielectric layer formed on the recording film, an Si reflecting film on the second dielectric layer, and an A1 metal reflecting film and a UV resin layer sequentially formed on the Si reflecting film.
