| 英文摘要 | A disc recorder/reproducer comprising a laser drive circuit (15) which can regulate the power of laser light by supplying a drive signal to an optical head (4), an error correction circuit (11) for detecting the error rate of a reproduced signal, and a system controller (10) for controlling operation of the laser drive circuit based on the output from the error correction circuit. The system controller registers the relation between an optical laser power where the error rate does not exceed a predetermined value and the disc temperature on a management table. At the time of setting a laser power, an optimal laser power can be set depending on the variation of disc temperature by reading out an optimal laser power corresponding to the of disc temperature from the management table. |
