Abstract

본 발명은 멀티디스크트레이에 디스크판별센서를 설치하고서 디스크의 장착과 동시에 디스크의 종류를 판별하여 픽업을 이송시킴으로써 초기기동시간을 단축할 수 있고, 또한 서로 다른 종류의 디스크가 2장이상 장착된 경우에 에러신호를 발생시킴과 동시에 트레이로딩동작을 정지시키도록 된 멀티디스크플레이어의 디스크종류판별 및 기동시간단축방법을 제공하기 위한 것이다.The present invention can reduce the initial startup time by installing a disc discrimination sensor in a multi-disc tray and determining the type of disc and transferring the pickup at the same time, and also when two or more different types of discs are mounted. The present invention provides a method for disc type discrimination and shortening the start time of a multi disc player which generates an error signal and stops the loading operation.

이를 위해 본 발명은, 제1∼제4디스크판별센서(S1∼S4)가 온상태로 되어 있는지의 여부를 판단하여 온상태로 되어 있으면 카운트값을 1증가시킨 다음에 카운트값이 2이상의 값인지의 여부를 판단하는 제1 내지 제4단계와, 상기 제1 내지 제4단계중 어느 한 단계에서 카운트값이 2이상이라고 판단한 경우 트레이에 디스크가 2개이상 장착되어 있다고 판단하고서 에러신호발생부(30)가 에러신호를 발생시키도록 함과 더불어 트레이로딩부(20)가 동작하지 못하도록 하는 제5단계, 상기 제4단계에서 카운트값이 2이상의 값이 아니라고 판단한 경우 상기 트레이로딩부(20)에 트레이를 내부로 이송시키도록 함과 동시에 픽업이송부(40)에 픽업을 초기데이터독출위치로 이송시키도록 하는 제6단계를 구비하여 이루어진 것이다.(제4도)To this end, the present invention determines whether the first to fourth disk discrimination sensors S1 to S4 are in the on state, and if it is in the on state, increases the count value by one and then determines whether the count value is two or more. If it is determined that the count value is two or more in any one of the first to fourth steps and the first to fourth steps, the error signal generator determines that two or more disks are mounted in the tray. 30) to generate an error signal and to prevent the tray loading unit 20 from operating, if it is determined that the count value is not more than two in the fourth step, the tray loading unit 20 And a sixth step for transferring the tray to the inside and simultaneously transferring the pickup to the initial data reading position in the pickup transport unit 40 (FIG. 4).

Claims (2)

제1디스크판별센서(S1)가 온상태로 되어 있는지의 여부를 판단하여 온상태로 되어 있으면 카운트값을 1증가시킨 다음에 카운트값이 2이상의 값인지의 여부를 판단하는 제1단계와, 상기 제1단계에서의 카운트값이 2이상의 값이 아닌 경우 제2디스크판별센서(S2)가 온상태로 되어 있는지의 여부를 판단하여 온상태로 되어 있으면 카운트값을 1증가시킨 다음에 카운트값이 2이상의 값인지의 여부를 판단하는 제2단계, 상기 제2단계에서의 카운트값이 2이상의 값이 아닌 경우 제3디스크판별센서(S3)가 온상태로 되어 있는지의 여부를 판단하여 온상태로 되어 있으면 카운트값을 1증가시킨 다음에 카운트값이 2이상의 값인지의 여부를 판단하는 제3단계, 상기 제3단계에서의 카운트값이 2이상의 값이 아닌 경우 제4디스크판별센서(S4)가 온상태로 되어 있는지의 여부를 판단하여 온상태로 되어 있으면 카운트값을 1증가시킨 다음에 카운트값이 2이상의 값인지의 여부를 판단하는 제4단계, 상기 제1 내지 제4단계중 어느 한 단계에서 카운트값이 2이상이라고 판단한 경우 트레이에 디스크가 2개이상 장착되어 있다고 판단하고서 에러신호발생부(30)가 에러신호를 발생시키도록 함과 더불어 트레이로딩부(20)가 동작하지 못하도록 하는 제5단계, 상기 제4단계에서 카운트값이 2이상의 값이 아니라고 판단한 경우 상기 트레이로딩부(20)에 트레이를 내부로 이송시키도록 함과 동시에 픽업이송부(40)에 픽업을 초기데이터독출위치로 이송시키도록 하는 제6단계로 구비하여 이루어진 것을 특징으로 하는 멀티디스크플레이어의 디스크종류판별 및 기동시간단측방법.A first step of determining whether the first disk discrimination sensor S1 is in the on state and increasing the count value by one, and then determining whether the count value is two or more, and If the count value in the first step is not greater than or equal to 2, it is determined whether the second disk discrimination sensor S2 is in the on state.
