기록매체에 미리 형성된 기록트랙상에 트랙방향에 따라 주정보를 기록하는 신호기록방법에 있어서, 상기기록매체의 소정 영역에는 상기 주정보의 클록성분의 주파수인입용의 동기신호가 트랙폭방향변위에 의해 미리 기록형성되고, 상기 소정 영역의 상기기록트랙상에 상기 주정보의 클록성분의 위상인입용 신호를 기록하는 것을 특징으로 하는 신호기록방법.A signal recording method for recording main information in a track direction on a recording track previously formed on a recording medium, wherein a predetermined area of the recording medium has a synchronization signal for frequency incorporation of a clock component of the main information in a track width direction displacement. Recording-formed in advance and recording a phase in signal for the clock component of the main information on the recording track in the predetermined area. 기록트랙상에 기록되는 주정보의 클록 성분의 주파수인입용 동기신호가 트랙폭방향변위에 의해 미리 소정영역에 기록형성되어 이루어지는 기록매체의 상기 소정 영역의 상기 트랙상에 소정패턴의 신호가 기록된 기록매체에 의해 상기 주정보를 재생할 때에,상기 트랙폭방향변위에 의해 기록형성된 동기신호의 재생신호를 클록주파수인입에 사용하고, 상기 주정보의 재생신호를 클록의 위상인입에 사용하는 것을 특징으로 하는 신호재생방법.A signal of a predetermined pattern is recorded on the track of the predetermined area of the recording medium, in which a frequency-accepting synchronization signal of the clock component of the main information recorded on the recording track is recorded in a predetermined area in advance by the track width direction displacement. When reproducing the main information by a recording medium, the reproduction signal of the synchronization signal recorded by the track width direction displacement is used for clock frequency input, and the reproduction signal of the main information is used for phase input of the clock. Signal reproduction method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
