摘要： A recorded stream generator generates a data block stream in synchronism with the phase of a recording clock, from the input data. The recorded stream generator further generates, for each predetermined data unit constituting the data block stream, a data phase reference pulse indicative of the phase of the data unit. An inserting section inserts a VFO signal into a predetermined amount (32 sectors) of the data block stream, the VFO signal having a length of time corresponding to a difference in phase between an wobble address phase signal and a data phase reference pulse. The inserting section thus provides a data stream DST consisting of the VFO signals and the data block streams. An LD uses light beams to record the data stream on an optical disk.

摘要： According to one embodiment, a frequency detector detects a frequency error between a frequency of a reproduction signal supplied from an analog to digital converter and a frequency of a clock for conversion. A loop filter controls an oscillation frequency of a voltage control oscillator based on the frequency error and a phase error detected by a phase comparator. An adaptive equalizer equalizes a waveform of the reproduction signal supplied from the analog to digital converter to obtain a response of a predetermined PR class. A Viterbi decoder decodes the waveform equalized signal into binary data by maximum likelihood sequence estimation. A clock supply control circuit stops supply of a clock to at least the phase comparator, the adaptive equalizer and the Viterbi decoder in a case where the frequency error is larger than a designated error.
