    摘要： A pit data generation circuit generates a first clock signal synchronized with pit data and a pit synchronization signal from a sum read signal obtained by reading the length of a pit. A division circuit generates a second clock signal by frequency-dividing the first clock signal. The division circuit is reset by the pit synchronization signal, and is capable of adjusting the phase of the second clock signal.

    摘要： On a disc master DS, a record mark having a variable length according to the first data is formed at a displaced position to which the record mark is displaced, in a direction crossing the reading direction thereof, according to a wobble signal obtained by modulating the second data in a predetermined modulating method. A second start position at which the head of the second data is recorded is away from a first start position at which the head of the first data is recorded by a predetermined value.

    摘要： 1 An optical recording medium for accurately deriving the address information or the disc rotation control information despite narrow track pitch and for recording signals to a high density, and a method and apparatus for recording and/or reproducing such optical recording medium. The optical recording medium has a wobbled groove and pits formed at a pre-set interval in an area between turns of the wobbled groove. The recording/reproducing method includes controlling rotation of the optical recording medium by a wobbled signal from the groove and detecting the position on the optical recording medium of a recording signal by pit signals detected from the pits. The recording/reproducing apparatus includes a detection device for detecting the wobbled signal from the groove and a detection device for detecting pit signals from the pits. The rotation of the optical recording medium is controlled by the wobbled signals detected from the groove and the position on the optical recording medium of the recording signal is detected by the pit signal detected from the pits.

    摘要： A clock signal generating system of the present invention is provided for recording information on a disc. The disc has a plurality of recording tracks wobbled by a wobble signal having a predetermined frequency and a plurality of prepits disposed at positions having a predetermined phase relation with respect to a phase of the wobble signal. A clock signal is generated based on the wobble signal. A prepit signal is produced from the prepit. The phase of the wobble signal is compared with a phase of the prepit signal, thereby generating a phase adjusting signal. The phase of the clock signal is adjusted based on the phase adjusting signal. A recording clock signal for recording the information is produced by an adjusted clock signal.
