发明名称 Optical disc device
摘要 Provided is an optical disc device in which adjustment precision of recording laser power is improved without complication of a processing sequence during recording operation. In response to a recording start instruction, OPC is executed using an inner disc drive zone to set an initial value of recording laser power Pws. Then, when a recording instruction REC( 1 ) is issued, recording is successively performed from the head of a data area using the laser power Pws. After that, when an intermittent standby period T is set, sample data is recorded at the number of times corresponding to the intermittent standby period T in a next recording position, and R-OPC is executed. Therefore, the recording laser power Pws is set again. Then, when a second recording instruction REC( 2 ) is issued, recording is successively performed from a next recording position, that is, a position next to an end portion of data recorded by the first recording instruction REC( 1 ) using the reset laser power Pws. At this time, data corresponding to a head portion of the second recording instruction REC( 2 ) is overwritten on sample data in the head of the recording position.
