Abstract

본 발명은 디스크 구동장치에서의 디스크 검사방법에 관한 것이다. 본 발명은 (가)픽업장치를 TOC 영역에 이동시킨 후 데이타 판독을 위한 포커스 동작을 실행시키는 단계; (나)포커스 동작이 완료된 후, 디스크의 유·무를 체킹하는 단계; (다)디스크가 있으면, 스핀들 모터를 구동시켜 디스크를 회전시키는 단계; (라)디스크의 회전속도가 설정된 회전속도에 도달할 때까지의 소요 시간을 측정하는 단계; (마)상기 측정된 소요시간이 설정된 소요시간보다 작은지의 여부를 판별하는 단계; 및 (바)상기 측정된 소요 시간이 설정된 소요시간보다 작으면 외경이 작은 디스크로 인식하고, 측정된 소요시간이 설정된 소요시간보다 크면 외경이 큰 디스크로 인식하는 단계를 포함한다.The present invention relates to a disc inspection method in a disc drive device. The present invention includes the steps of: (a) moving a pickup device to a TOC area and then executing a focus operation for reading data; (B) checking the presence or absence of the disc after the focus operation is completed; (C) if the disk is present, driving the spindle motor to rotate the disk; (D) measuring the time required for the rotational speed of the disk to reach the set rotational speed; (E) determining whether the measured time required is less than a set time required; And (f) recognizing the disk as having a smaller outer diameter when the measured time required is smaller than the set required time, and recognizing the disk as having a larger outer diameter when the measured time required is larger than the set time.

이와 같이, 디스크의 회전속도를 측정하여 디스크를 검사하게 되므로, 검사시간이 종래의 검사방식에서보다 훨씬 빠르며, 따라서 디스크 검사단계에서부터 디스크 구동장치의 후속동작 준비단계까지의 소요시간을 한층 단축시킬 수 있어 업무상의 능률을 향상시킬 수 있는 장점이 있다.In this way, since the disk is inspected by measuring the rotational speed of the disk, the inspection time is much faster than in the conventional inspection method, and thus the time required from the disk inspection step to the preparation stage for the subsequent operation of the disk drive device can be further shortened. There is an advantage to improve the work efficiency.
