摘要： A method and device for generating a clock signal accurately synchronized with a wobble signal including jitter even if there are manufacturing differences between voltage controlled oscillators. The clock signal generation device includes a voltage controlled oscillator for generating a clock signal corresponding to each of a plurality of oscillation characteristics. The clock signal generation device applies a test voltage to a voltage controlled oscillator with a voltage control device and sequentially identifies a plurality of oscillation characteristics set for the voltage controlled oscillator. The clock signal generation device selects one of the identified oscillation characteristics that has a frequency range with a generally middle part in which the frequency of a wobble signal is located and has a smaller gain.

摘要： A data reproduction apparatus is provided to supply audio data without sound skipping caused by positional deviation in read position, while avoiding an increase in circuit area. In one embodiment, the data reproduction apparatus includes a reading unit for optically reading data recorded on a recording medium. A first signal processing circuit produces a format data signal based on the data read by the reading unit. A second signal processing circuit performs a demodulation process on the format data signal to produce a demodulated format data signal including main data and subcode data. The second signal processing circuit also subjects the main data signal to a decoding process to produce a reproduced data signal. A buffer memory temporally stores the reproduced data signal. A shockproof controller controls the writing and reading of the reproduced data signal into and from the buffer memory. An operation controller causes the shockproof controller to stop the writing of the reproduced data signal in the buffer memory and causes the reading unit to repeat the reading of the data associated with the interrupted format data signal when the format data signal produced by the first signal processing circuit is interrupted. Further, when one of the operation controller and the shockproof controller receives the subcode data signal from the second signal processing circuit, the shockproof controller restarts the writing into the buffer memory of the reproduced data signal associated with the repeated reading of the data associated with the interrupted format data signal.

摘要： A CD-ROM decoder for processing digital data while buffering the digital data in a buffer RAM. The CD-ROM decoder includes a host interface for storing the digital data in the buffer RAM. An EDC processing circuit generates an error detection code using the digital data read from the buffer RAM in a block unit. An ECC processing circuit generates an error correction code with the digital data and the error detection code. An internal RAM stores the digital data and adds the error detection code and the error correction code to the digital data when storing the digital data. A digital signal processor outputs the digital data, the error detection code, and the error correction code that are stored in the internal RAM in a block unit.
