Abstract

CD중 CDV를 빠르게 인식하여 구동시킬수 잇도록한 LDP의 디스크 인식방법에 관한 것으로, 턴테이블에 있는 디스크의 종류를 파악하여 파악된 디스크에 따라 디스크를 플레이시키기 위해 픽업위치이동부와, 픽업정보판독부를 구비한 LDP의 디스크인식방법에 있어서, 픽업의 위치를 이동하여 LD의 유무를 인식하는 단계; LD가 없을 경우 픽업위 위치를 계속 이동하여 CD를 인식하는 단계; 인식된 CD가 CDV인지를 판단하는 단계; 및 CDV인 경우 LD위치로 픽업이동중 CDV의 시작부분을 감지하고 픽업을 세팅시켜 플레이시키는 단계로 이루어진다.The present invention relates to a disk recognition method of an LDP that enables the CDV to be quickly recognized and driven among CDs, and includes a pickup position moving unit and a pickup information reading unit for identifying the type of the disc on the turntable and playing the disc according to the identified disc. A disk recognition method of an LDP, comprising: recognizing the presence or absence of an LD by moving a pickup position; If there is no LD, continuously moving the position on the pickup to recognize the CD; Determining whether the recognized CD is a CDV; And in the case of CDV, detecting the beginning of the CDV during the pickup movement to the LD position and setting the pickup to play.

CDV의 인식후 픽업을 CDV의 시작위치로 빠르게 이동시킬 수 잇으므로 디스크종류에 따른 LDP의 리드인타임을 개선시킬 수가 있다.After the CDV is recognized, the pickup can be quickly moved to the start position of the CDV, thereby improving the lead time of the LDP according to the disc type.
