광 디스크 드라이버의 고속 서치방법High speed search method of optical disk driver

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는, 본 발명이 적용되는 광 디스크 드라이버의 회로도.1 is a circuit diagram of an optical disk driver to which the present invention is applied.

제2도는, 본 발명 플로우 챠트.2 is a flowchart of the present invention.

Claims (1)

광학헤드(6)로부터 검출된 신호는 데이타 복조부(4)에 의해 피포메모리(3)로 저장되고, 트래킹 펄스 발생부(9)는 트랙이 이동될 때마다 발생하는 펄스를 트랙카운터(2)로 인가하며, 시스템을 제어하기 위한 마이크로 프로세서(1)와 공디스크 콘트롤러(10) 및 프래킹코일(L)을 구동하기 위한 디지탈 아나로그 변환기(8)와 증폭기(11)와 트래킹포일 구동부(12)를 구비한 광 디스크 드라이버의 서치를 수행함에 있어서, 트랙의 이동거리를 계산하여 트랙카운터(2)에 프리세트시키고, 트랙카운터(2)가 0로 될때까지 광학헤드(6)와 연결된 스텝모터(7)를 구동한 다음 다시 현재 위치를 확인하여 트래킹 코일(L)로 이동가능한 거리까지 스텝모터(7)로 헤드의 위치를 이동시키며, 트래킹 코일(L)로 이동가능한 거리내에서 트랙카운터(2)를 다시 프리세트 시키고 트랙카운터(2)가 0이 될때까지 트래킹 코일(L)을 구동하여 트랙카운터(2)가 0일때 타임 딜레이를 1회 실시함으로써 정확한 위치를 확인한 후 포커싱 서어보와 트래킹 서어보를 동작시켜 시크동작을 수행하는 것을 특징으로 하는 광 디스크 드라이버의 고속 서치방법.The signal detected from the optical head 6 is stored by the data demodulator 4 into the storage memory 3, and the tracking pulse generator 9 outputs a pulse generated every time the track is moved. Digital analog converter (8), amplifier (11), and tracking foil driver (12) for driving the microprocessor (1), the blank disk controller (10), and the cracking coil (L) for controlling the system. In performing the search of the optical disk driver having a), a step motor connected to the optical head 6 is calculated by presetting the track moving distance to the track counter 2, until the track counter 2 becomes zero. (7) and then check the current position again to move the position of the head to the step motor (7) to the distance that can be moved to the tracking coil (L), within the distance that can be moved to the tracking coil (L) 2) Preset again and track counter (2) The tracking coil (L) is driven until it reaches zero, and the track counter (2) performs a time delay once, so that the correct position is confirmed by operating the focusing servo and the tracking servo. High speed search method of optical disk driver. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
