摘要： A recording method for an optical disc drive and an optical disc drive capable of preventing a light source of a laser beam or a laser driving portion from becoming uncontrollable as they are heated to high temperatures above their compensation temperatures, and thereby enabling recording to be continued in a stable manner without being interrupted or stopped until it ends. A surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device on the basis of the surrounding temperature measuring result and the correlating result, wherein the recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.

摘要： A signal processing device for optical disks includes a reflected light process section configured to convert reflected light received by an optical pickup into an electric signal based on a first gain, wherein the optical pickup emits laser light to an optical disk and receives reflected light from the optical disk; a servo signal generation section configured to generate a servo signal by using the electric signal generated by the reflected light process section; a servo signal control section configured to control the servo signal so that a change in the amplitude of the servo signal, in response to an increase or decrease of the amount of the reflected light from the optical disk, is suppressed using an attenuator that attenuates the servo signal generated by the servo signal generation section by a factor of a second gain; and a gain setting section configured to set the first gain to the reflected light process section and the second gain to the servo signal control section substantially simultaneously.
