1회에 최대 m트랙점프를 구동할 수 있는 컴팩트 디스크 플레이에서 프로그램 모드시 패스트 백워드 서치 방법에 있어서, 현재 곡의 시작 위치인가 검사하며, 아닐시 4트랙을 백방향으로 점프한후 리턴하는 제1과정과, 상기 제1과정에서 프로그램 플레이 모드에서 현재곡이 시작 위치일시 전회의 프로그램 곡번호를 인식했는가 검사하며, 아닐시 m트랙점프한후 리턴하는 제2과정과, 상기 제2과정에서 전회의 프로그램 곡을 번호를 인식했을시 해당 곡의 마지막 통과 위치여부를 확인하는 제3과정과, 상기 제3과정 수행후 전회의 프로그램 곡의 마지막 위치를 통과했는가 검사하며 아닐시 현상태의 트랙점프를 실시한후 리턴하는 제4과정과, 상기 제4과정에서 전회 프로그램 곡의 마지막 위치 통과시 1회 통과인가 검사하며, 1회 통과일시 방향을 전환하여 제1트랙수로 감소 점프구동한후 리턴하는 제5과정과, 상기 제5과정에서 아닐시 2회 통과인가 검사하며, 2회 통과일시 방향을 전환하여 제2트랙수로 감소점프 구동하는 제6과정과, 상기 제6과정에서 아닐시 3회 통과인가 검사하며, 3회 통과일시 제3트랙수로 감소 점프 구동한후 리턴하는 제7과정과, 상기 제7과정에서 아닐시 4회통과인가 검사하며, 4회 통과일시 방향 전환하여 제4트랙수로 감소 점프구동한후 리턴하는 제8과정과, 상기 제8과정에서 아닐시 전회의 프로그램 곡의 마지막 위치를 서치완료 했음을 기록하고 리턴하는 제9과정으로 이루어짐을 특징으로 하는 프로그램 모드시 패스트 백워드 서치 기능 개선방법.In the fast backward search method in the program mode in a compact disc play capable of driving a maximum m track jump at a time, the method checks whether the current track is at the beginning, and if it does not, jumps 4 tracks in the back direction and returns. In the first step, the second step of checking whether the current song is recognized in the program play mode in the program play mode and the previous program song number, and if not, returning after m-track jumping; The third process of checking whether the last track position of the song is passed when the program song of the program is recognized, and whether the last position of the previous program song has passed after the third process is performed, and if not, the track jump of the present state is performed. After the fourth process of returning, and the fourth process in the fourth process passes the last position of the previous program song checks whether the first pass, and the first pass date and time direction to switch the first A fifth step of returning after reducing jump driving by the number of tracks; and a sixth step of checking whether or not the second pass has been passed twice when the fifth step is not performed; In the sixth process, and checks whether three passes if not, and the seventh process of returning after the reduced jump drive to the number of the third track at the third pass date and time, and checks whether the four passes if not in the seventh process, Eighth step of changing the direction of the four passes and then return to the fourth track after reducing the number of jumps; and the ninth step of recording and returning the last position of the last program song when the non-null program is completed in the eighth step. Method for improving the fast backward search function in the program mode, characterized in that made. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
