Signal processing apparatus and signal processing method |
摘要 |
An encoder & decoder unit for encoding data to be recorded has a data-supply-start-signal-generating circuit for generating an ATTX signal requesting that an operation to supply the data to be recorded to the encoder & decoder unit be started by counting 88.5 frames starting at detection of the rising edge of a 1F.START signal by an address decoder. The encoder & decoder unit also includes a laser-power-switching-signal-generating circuit for generating an ATRECP signal making a request for switching of a laser power by counting 49 frames starting at detection of the rising edge of an FD.START signal by the address decoder. A system controller thus needs to generate an RECXPB signal requesting that a recording operation from the next cluster be started only at a precision of about 2 seconds with respect to the period of 1 cluster. In this way, it is possible to provide a degree of precision higher than execution of timing control by using the system controller external to the encoder & decoder unit.
