Abstract

본 발명은 광자기 디스크에서 자기적 초해상(magnetically induced Super resolution)을 이룩하기위해 재생층과 기록층 사이에 재생 보조층을 형성시킴으로서 작은 bit에서도 재생 신호품질이 뛰어나고 기록밀도가 향상되는 광자기 디스크에 관한 것으로 기판상에 제1보호층, 재새층, 기록층, 제2보호층이 순차적으로 적층된 구조를 포함한 것에 있어서, 재생층과 기록층 사이에 재생보조층이 형성됨을 특징으로 하는 초해상용 광자기 디스크에 관한 것이다.The present invention provides a magneto-optical disc with excellent reproduction signal quality and improved recording density even at a small bit by forming a reproduction auxiliary layer between the reproduction layer and the recording layer to achieve magnetically induced super resolution in the magneto-optical disc. A super-resolution for comprising a structure in which a first protective layer, a new layer, a recording layer, and a second protective layer are sequentially stacked on a substrate, wherein a reproduction auxiliary layer is formed between the reproduction layer and the recording layer. Relates to a magneto-optical disk.
