Abstract

본 발명은 B면에 형성된 나선형 트랙의 데이타 기록 방향을 외측에서 내측으로 이어지게 변경하여 플레이어에 의해 레이져 디스크를 재생할 때, A,B면 재생에 관계없이 스핀들 모터를 계속 일방향으로만 회전시키도록 함에 따라 A면 재생 완료 후 B면을 재생하기 까지 걸리는 시간 손실을 줄일 수 있도록 한 것이다.The present invention changes the data recording direction of the spiral track formed on the B side from the outside to the inside, so that when the player plays the laser disk, the spindle motor continues to rotate in only one direction regardless of the A and B side reproduction. This is to reduce the time loss from the completion of A side playback to the B side playback.

이를 위해 본 발명은 A면(1)에는 저면에서 보았을 때 반시계 방향의 나선형 트랙(2)이 형성됨과 함께 B면(1a)에는 평면에서 보았을 때 시계 방향의 나선형 트랙(2a)이 형성된 것에 있어서, 상기 A면(1)에 형성된 나선형 트랙(2)에 내측에서 외측으로 이어지게 데이타를 기록하고 B면(1a)에 형성된 나선형 트랙(2a)에는 외측에서 내측으로 이어지게 데이타를 기록하여서 된 것이다.To this end, the present invention provides a counter-clockwise spiral track 2 formed on the A surface 1 and a counterclockwise spiral track 2a formed on the B surface 1a. The data is recorded from the inner side to the outer side on the spiral track 2 formed on the A surface 1, and the data is recorded from the outer side to the inner side on the spiral track 2a formed on the B surface 1a.

Claims (1)

A면(1)에는 저면에서 보았을 때 반시계 방향의 나선형 트랙(2)이 형성됨과 함께 B면(1a)에는 평면에서 보았을 때 시계 방향의 나선형 트랙(2a)이 형성된 것에 있어서, 상기 A면(1)에 형성된 나선형 트랙(2)에 내측에서 외측으로 이어지게 데이타를 기록하고 B면(1a)에 형성된 나선형 트랙(2a)에는 외측에서 내측으로 이어지게 데이타를 기록하여서 됨을 특징으로 하는 레이져 디스크.In the A surface 1, the spiral track 2 is formed in the counterclockwise direction when viewed from the bottom surface, while the spiral surface 2a in the clockwise direction is formed on the B surface 1a in view of the A surface ( And recording data extending from the inside to the outside on the spiral track (2) formed in 1) and recording the data running from the outside to the inside on the spiral track (2a) formed on the B surface (1a). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
