Abstract

본 발명은 기록 매체에 관한 것으로 상세히는 소거 특성이 개선된 상 변화 광기록 매체(Phase change optical recording medium)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium, and more particularly, to a phase change optical recording medium having improved erase characteristics.

본 발명의 광기록 매체는, 기판과; 상기 기판 위에 마련되는 기록막과; 상기 기록막의 상하에 마련되는 유전체층과; 상기 기록막과 상기 상하 유전체층의 사이에 개재되는 것으로 Pt, Pd Au, Ag 중의 선택된 적어도 어느 하나의 물질로된 금속층을 구비한다.An optical recording medium of the present invention includes a substrate; A recording film provided on the substrate; A dielectric layer provided above and below the recording film; A metal layer interposed between the recording film and the upper and lower dielectric layers and made of at least one material selected from Pt, Pd Au, and Ag.

이러한 본 발명에 의하면, 기록막과 유전체막 사이에 화학적으로 안정한 금속층이 마련되게 있기 때문에 금속막과 유전체막의 계면이 안정화되기 때문에 반복적 기록/소거 특성의 열화가 억제되고, 또한 전술한 바와 같이 결정화시, 결정핵으로의 작용에 의해 소거시 활성화 에너지 감속에 의한 소거시간 단축 또는 소거 레이저의 출력을 감소시킬 수 있게 된다.According to the present invention, since the chemically stable metal layer is provided between the recording film and the dielectric film, the interface between the metal film and the dielectric film is stabilized, so that deterioration of the repetitive recording / erasing characteristics is suppressed, and as described above, In addition, by the action of the crystal nuclei, it is possible to shorten the erasing time or decrease the output of the erasing laser due to the activation energy deceleration during erasing.
