디스크 재생장치Disc player

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도 본 발명에 관련된 디스크 재생장치의 일예를 표시하는 블록접속도.1 is a block connection diagram showing an example of a disc reproducing apparatus according to the present invention.

제2도 제1도의 예의 동작설명에 제공되는 프로챠트.FIG. 2 is a flowchart provided in the operational description of the example of FIG.

Claims (1)

정보가 나선형의 기록트랙을 가지고 기록된 디스크로부터 상기 정보를 독해하는 독해수단과 펄스신호에 의해 구동되어, 상기 독해수단을 상기 펄스신호에 따라서 상기 디스크의 반경방향으로 이동케하는 스텝핑 모터와 상기 독해수단이 상기 기록트랙의 시단부에 위치할 때 크리어되어, 상기 스텝핑 모터를 구동하는 펄스신호를 카운트하므로서, 상기 독해수단의 상기 디스크상에 있어서의 위치를 나타내는 제1의 위치데이타를 발생하는 카운터와, 독해위치 지정신호를 받아서 그 독해위치 지정신호가 나타내는 상기 디스크상의 위치에 대응하는 제2의 위치데이타를 발생하고, 그 제2의 위치데이타와 상기 카운터로부터의 제1의 위치데이터와의 차의 데이터를 얻어, 그 차의 데이터에 대응하는 상기 스텝핑 모터 구동용의 펄스신호를 발생케하여 그 펄스신호를 상기 스텝핑 모터의 제어부에 공급하는 시스템 콘트롤부를 구비하고, 상기 스텝핑 모터가 상기 시스템 콘트롤부로부터의 펄스신호에 의해 구동되는 것으로 상기 독해수단의 상기 디스크상에 있어서의 위치가 상기 독해위치 지정신호가 나타내는 상기 디스크상의 위치에 근접되게끔 된 디스크 재생장치.The stepping motor and the readout, the information being driven by reading means and a pulse signal to read the information from a disc recorded with a spiral recording track, and causing the reading means to move in the radial direction of the disc in accordance with the pulse signal. A counter which is creeped when the means is located at the beginning of the recording track to generate a first position data indicating a position on the disk of the reading means by counting a pulse signal for driving the stepping motor; Receive a read position designation signal and generate a second position data corresponding to the position on the disc indicated by the read position designation signal, the difference between the second position data and the first position data from the counter; Obtains data, and generates a pulse signal for driving the stepping motor corresponding to the difference data; A system control section for supplying a switch signal to the control section of the stepping motor, wherein the stepping motor is driven by a pulse signal from the system control section so that the position on the disk of the reading means is determined by the reading position. And a disk player for bringing the signal closer to a position on the disk. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
