Title:
RECORDING APPARATUS AND REPRODUCING APPARATUS FOR DISK-SHAPED RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP3575099
Kind Code:
B2
Abstract:
PURPOSE: To obtain a recording apparatus and a reproducing apparatus whose power consumption can be reduced.
CONSTITUTION: The recording apparatus and the reproducing apparatus for a disk- shaped recording medium are constituted in such a way that, in a recording operation, data to be recorded, a 2T pattern for the correction of a recording dislocation and an 8T pattern for the setting of a threshold value used in the detection of a ternary value by partial response are recorded in the disk-shaped recording medium and, in a reproducing operation, recorded data is reproduced on the basis of the 2T pattern and the 8T pattern which have been reproduced. Then, in the recording operation, a clock controller 5 stops the supply of a clock to a data reproducing part 3 so as to be in a stop state, and, when no operation is required, it stopts the supply of a clock to a 2T pattern clock generation part 6, an 8T pattern generation part 7 or a data pattern generation part 8 so as to be in a stop state. In addition, in the reproducing operation, the clock controller 5 stops the supply of a clock to a recorded data formation part 2 so as to be in a stop state, and, when no operation is required, it stops the supply of a clock to a 2T pattern processing part 10, an 8T pattern processing part 11 or a data detection part 12 so as to be in a stop state.
