Abstract

본 발명은 광 디스크 및 광 디스크 기록/재생장치에 관한 것으로, 특히 디스크상의 산과 골의 트랙 각각에 고밀도로 정보신호를 기록할 수 있도록 함과 아울러 이의 정보신호를 기록 및 재생할 수 있도록 하는 광 디스크 및 광 디스크 기록/재생장치에 관한 것으로, 디스크상의 산과 골의 신호트랙에 각각 정보신호를 기록할 수 있도록 하며, 산과 골사이의 측면 접촉선에 개선된 워블링의 파일럿신호를 기록하여 디스크의 회전속도를 제어할 수 있도록 함과 아울러 어드레스 정보를 기록할 수 있게 하여 기록밀도를 향상시키며, 또한 재생전용 디스크의 신호규격과 동일하게 기록하도록 함으로써 디스크간의 재생호환성을 유지할 수 있는 광 디스크와 기록/재생 장치를 제공하는데 목적이 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc and an optical disc recording / reproducing apparatus, and more particularly, to an optical disc capable of recording information signals at high density on each of tracks of hills and valleys on the disc, and to recording and reproducing the information signals thereof. An optical disc recording / reproducing apparatus, wherein information signals can be recorded on the mountain and valley signal tracks on the disc, and an improved wobbling pilot signal is recorded on the side contact line between the mountain and the valley to record the rotation speed of the disc. And recording / reproducing apparatus that can maintain recording compatibility between discs by controlling the control of the disc, and by recording address information to improve recording density and recording the same as the signal standard of the disc for exclusive use of the disc. The purpose is to provide.
