摘要： An apparatus for reproducing data includes a branch metric computation unit and a plurality of parallel computation units. Each parallel computation unit includes path metric computation units that compute path metric values based on branch metric values. Path metric memories store the path metric values to be used in a next following path metric computation, and reliability computation units compute path reliability. Modified-path generating units generate an inverted path that is inverse to a path indicated by an output of the reliability computation units as having low reliability. If any one of the modified-path generating units generates the inverted path, a corresponding one of the path metric computation units stores a path metric value corresponding to the inverted path in a corresponding one of the path metric memories as a path metric value to be used in a next following path metric computation.

摘要： The present invention realizes stable and more proper data reproduction even when a reproduced signal varies locally due to a noise or includes a steady distortion. In a data reproduction control method and apparatus, and an optical disk unit that adjust sampled values, in sampling a signal reproduced from a recording medium recorded with data, the frequencies of the levels of quantized data are counted, a histogram of the frequencies of the levels is created based on the counting results, and more accurate reproduced data is obtained by means of a distribution of the frequencies of the levels in the histogram.

摘要： A disc apparatus has a cartridge loading/unloading mechanism to perform a loading operation for attaching an optical disc enclosed in a cartridge inserted from an outside to a rotary shaft of a spindle motor and an unloading operation for removing the optical disc from the rotary shaft of the spindle motor and for ejecting the cartridge to the outside. The loading operation of the cartridge loading/unloading mechanism is executed by the rotation of one direction of a load motor. The unloading operation of the cartridge loading/unloading mechanism is executed by the rotation in the reverse direction of the load motor. A drive current of the load motor is turned on or off at a short period, thereby adjusting so as to optimize a drive torque. When an exchangeable optical disc is loaded, a motor is activated, an initialization control is executed during the acceleration, and after a motor rotational speed reached a specific speed, the apparatus enables the writing/reading operations to be executed. When a voice coil motor is driven simultaneously with the spindle motor during the initialization adjustment, the drive current of the spindle motor is limited.
