Abstract
광디스크 플레이어에 있어서 광디스크 플레이어 픽업수단에 관한 것으로, 특히, 정보기록매체인 광디스크의 형태가 사각인 사각형 광딧크 플레이어의 픽업수단 이송방법에 관한 것이다. 고속 access시 픽업수단을 트랙에 대해 횡방향으로 이동시키기 위한 제2슬레드모타 고속 access 구동과정과, 상기 제2슬레드모타 고속 access 구동과정후 광디스크상의 정보데이타를 정상적으로 재생하기 위해 트랙을 따라 종방향으로 픽업수단을 이송하는 제1슬레드모타 구동과정과, 제1슬레이드 모타 구동과정후 마이콤이 트랙의 종방향 끝단에 기록되어 있는 체크데이타를 인지하여 제1슬레드모타 회전방향전환 및 픽업수단 1트랙점핑 과정으로 이루어짐을 특징으로 한다. 따라서 고속 access 후에도 PLL부에 대한 로킹시간에 대한 제어상 어려움이 없음으로 고속 access가 부가되는 장치에 있어서 제어상 이점이 있다.The present invention relates to an optical disc player pick-up means for an optical disc player, and more particularly, to a method for transferring pickup means for a rectangular optical disc player having a square shape of an optical disc as an information recording medium. A second sled motor high speed access driving process for moving the pickup means laterally with respect to the track during high speed access, and a second sled motor high speed access driving process after the second sled motor high speed access driving process; The first sled motor driving process for transporting the pick-up means in the direction and the first sled motor rotation direction switching and pick-up means by recognizing the check data recorded at the longitudinal end of the track after the first slave motor driving process. It is characterized by consisting of one track jumping process. Therefore, there is no control difficulty in locking time for the PLL unit even after the high speed access, so there is a control advantage in the apparatus to which the high speed access is added.
