Claims (1)

디스크에 기록된 정보를 재생시키는 장치를 구성함에 있어서 광복사발생원으로 부터 복사되는 복사선속을 받아 정보트랙을 판독하기 위해 디스크에 있는 정보트랙상에 신속을 직진시키게끔 판독 헤드를 구성하고, 트랙에 의하여 조절된 선속으로부터 정보를 도출하는 장치를 설치하며, 판독헤드와 디스크 지지 요소 사이에 상대적인 운동을 하도록 하는 장치 및 판독헤드에 대하여 선속의 경로를 조절할 수 있는 장치를 구성함을 특징으로 하는 비데오 디스크 플레이어.In constructing a device for reproducing information recorded on a disk, a readhead is configured to quickly go straight on the information track on the disk in order to read the information track by receiving the radiation beam copied from the optical radiation source. A video disk, characterized in that it has a device that derives information from the speed of the ship adjusted by this method, and comprises a device that allows relative motion between the readhead and the disk support element, and a device capable of adjusting the path of the ship speed with respect to the readhead. player. ※ 참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed according to the content of the first application.
