摘要： In step S1, the address generator generates address information composed of a sync signal which is recorded on an optical disc, address data and an error correction code for the address data, pre-encodes and supplies it to a modulator. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. In step S2, the modulator makes MSK modulation of the carrier signal supplied from the carrier signal generator on the basis of the pre-encoded address information supplied from the address generator, and supplies a resultant MSK modulation signal to a wobbling unit. In step S3, the wobbling unit forms, on the optical disc, a spiral groove wobbled adaptively to the MSK modulation signal supplied from the modulator. In this optical disc, a given address can be accessed quickly and accurately.

摘要： There is provided an optical disc having preformed thereon a spiral wobbled track as a grove and/or land along with data is to be recorded. The track is wobbled for a series of predetermined signal units each composed of an FSK information bit part based on a waveform resulted from FSK modulation of information bit and a singe-frequency part based on a waveform of a single frequency. The FSK modulation uses two different frequencies of which the one is the same as the single frequency and the other is different from the single frequency. These different frequencies are in such a relation that each of them has an even number of wobbles and an odd number of wobbles alternately in a predetermined cycle.

摘要： Disclosed are an optical disk recording and reproducing apparatus, a remote controller, and a content management method capable of allowing a user to easily confirm contents recorded on an optical disk, wherein an optical disk is integrally provided with a read-only RFID tag that records only a disk ID to identify the optical disk as an individual. When a content is recorded on the optical disk, a video recorder records disk management information including the disk ID of the optical disk and index information about the content. After the content is recorded, a remote controller noncontactly reads the disk ID from the RFID tag of the optical disk and transmits the disk ID to the video recorder. The video recorder extracts index information corresponding to the received disk ID from the disk management information and displays the index information in a list.

摘要： 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 servo apparatus of an optical disc, comprises an amplitude detector for detecting an amplitude of a servo detection signal which was extracted by an optical pickup when servo focusing is operating. A gain control signal generator generates a gain control signal for providing a predetermined relation between the amplitude detected by the amplitude detector and a reference value. A controller holds the gain control signal generated by the gain control signal generator and controls the amplitude of the servo detection signal by the gain control signal upon a recording or reproducing operation by the optical pickup.
