Abstract

본 발명은 고밀도 기록을 위하여 피트-에지 기록을 이용하는 고밀도 광자기 디스크에서의 기록신호 보상 방법에 관한 것이다. 이르 위한 본 발명은, 피트-에지 기록을 이용하는 고밀도 광자기 디스크에서의 기록 신호 보상방법에 있어서, 기록 데이타를 엔코딩 수단을 통해 엔코딩하느 제1단계와, 상기 엔코딩 단계에서 엔코딩된 기록 데이타를 디지탈 신호 처리 수단 및 비대칭 가우시안을 통해 선형적인 아날로그 신호를 생성하는 제2단계, 및 상기 아날로그 신호를 입력받아 그 신호에 따라 광 출력을 상기 광자기 디스크상에 조사하는 제2단계를 포함하고, 상기 제2단계에서는 상기 기록 데이타의 패턴, 크기 및 간격을 검출한 후 그에 따라 상기 광자기 디스크의 마그네틱 도메인에 피크-에지가 아날로그적으로 기록되도록 알고리즘을 생성하여 재생시 지터가 발생되지 않도록 처리하는 것을 특징으로 한다.The present invention relates to a recording signal compensation method in a high density magneto-optical disk using pit-edge recording for high density recording. According to an aspect of the present invention, there is provided a recording signal compensation method in a high-density magneto-optical disc using pit-edge recording. A second step of generating a linear analog signal through a processing means and an asymmetric Gaussian; and a second step of receiving the analog signal and irradiating an optical output onto the magneto-optical disk according to the signal. In the step, after detecting the pattern, size and spacing of the recording data, an algorithm is generated such that peak-edges are recorded analogously in the magnetic domain of the magneto-optical disk, thereby processing to avoid jitter during reproduction. do.
