    摘要: This invention provides an optical disc device that can prevent the occurrence of an error in a starting position of a write operation due to off-tracking, and to avoid an unnecessary stop of the write operation during writing. A tracking error signal generator generates a tracking error signal from a signal which has been detected by an optical pickup, and a system controller detects off-tracking by comparing the tracking error signal with a threshold level, and turns control operation of a tracking servo controller off if the threshold level is exceeded. The off-tracking detection threshold level applied during a time period from completion of seek operation to a start of movement of the optical pickup to the starting position of the write operation is set to be lower than a threshold level applied during a time period of data recording.

    摘要: Within a disk recording/reproducing apparatus for improving a transfer rate when recording/reproducing, and an alternation process method for a disk for it, for recording or reproducing information onto/from an optical disk 100, while conducting a alternation on a defect block within a user data recording area into an alternation area, a controller 500 determines an alternation destination where data of an alternation origin are recorded therein, or a drive speed during the alternation process, upon basis of the position of the alternation origin on the optical disk, when conducting the alternation process. The alternation destination is determined upon basis of an intermediate position (rmid) of the disk, when the optical disk includes alternation areas on an innermost periphery and an outermost periphery thereof, and when it is conducted with CAV recording, on the other hand it is determined upon basis of an inner/outer peripheral rotation speed average position (rav) of the disk, when being conducted with CLV recording. Or, the drive speed during the alternation process is determined on the position of the alternation origin, upon basis of a drive speed inner peripheral rotation speed average position (rint), when the optical disk includes the alternation area only on the innermost periphery thereof, and when it is conducted with CLV recording.

    摘要: A method for detecting a starting position of each data recording block or sector on a data recording medium, such as an optical disk. A VFO pattern and a CRC code are recorded at a starting position of each of the sectors. The VFO pattern and the CRC code are utilized for detecting a starting position of each sector with no predetermined pattern or sector mark, on the recording medium, which is dedicated for the starting position detection. This improves data formatting efficiency of the recording medium while maintaining the accuracies of automatic focusing and tracking even in a system employing pit-edge recording/reproducing.

    摘要: An optical disk apparatus that does not need the intervention of a host apparatus, such as a host computer, performs a diagnostic method of checking the optical disk apparatus for diagnosis using a diagnostic optical disk medium. Upon the detection of the loading of a diagnostic optical disk medium into an optical disk apparatus, an optical head reads diagnostic information written beforehand on the diagnostic optical disk medium, and a diagnostic operation is carried out to diagnose a writing or reading operation of the optical disk apparatus under the control of a main control circuit without requiring the intervention of a host computer. The results of diagnosis are written on the diagnostic optical disk medium or provided in some other fashion. If the results are stored on the disk, the host computer makes reference to the stored results when necessary.
