Abstract
본 발명은 광자기 디스크의 기록/재생장치의 서치 방법에 관한 것으로, 특히 고속 검색이 가능하도록 광자기 디스크의 리드 인 영역과 프로그램 영역의 데이타 포멧을 변경하여 고속 검색이 가능하도록 한 광자기 디스크의 서치방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a search method of a recording / reproducing apparatus for a magneto-optical disc. In particular, the present invention relates to a magneto-optical disc capable of high-speed retrieval by changing the data format of the lead-in area and the program area of the magneto-optical disc. It is about search method.
이와 같은 본 발명의 광자기 디스크의 서치방법은 디스크의 리드 인 영역의 정보영역에 각 곡의 트랙정보를 기록함과 동시에, 프로그램 영역에도 각 곡의 서브코드 영역에 해당 트랙 정보를 기록하는 제1단계와, 서치모드가 선택되면 상기 제1단계에서 기록된 트랙정보로부터 현재 위치 트랙정보를 리드하는 제2단계와, 목표 위치의 트랙정보를 리드하는 제3단계와, 상기 제2, 제3단계에서 리드한 목표 위치의 트랙 정보에서 현재 위치의 트랙정보를 감산하여 그 위치로 이동하는 제4단계를 포함하여 이루어진 것이다.The magneto-optical disc search method of the present invention has a first step of recording track information of each song in the information area of the lead-in area of the disc, and recording the track information in the subcode area of each song in the program area. And a second step of reading current position track information from the track information recorded in the first step, a third step of reading track information of a target position when the search mode is selected, and the second and third steps. And the fourth step of subtracting the track information of the current position from the track information of the read target position and moving to the position.
