Abstract:
1. A recording method for an optical disc drive for recording information by irradiating a laser beam on a recording medium, comprising: measuring a surrounding temperature using a temperature measuring device; correlating a set surrounding temperature with a set recording rate for a multi-pulse recording operation using a correlating device; and changing a recording rate of the multi-pulse recording operation using a recording control device based on a surrounding temperature measuring result and a correlating result, wherein the recording rate of the multi-pulse recording operation is changed by changing a ratio of a recording operation time and a recording-stop operation time which are alternately repeated, a recording operation being performed by flashing pulses of the laser beam during the recording operation time, and a recording-stop operation being performed at as low a laser beam output as playback during the recording-stop operation time, and wherein a correlation between the set surrounding temperature and the set recording rate is such that the set recording rate is lower as the set surrounding temperature becomes higher, and the correlation between the set surrounding temperature and the set recording rate is such that at a start of recording, the recording rate corresponds to a case where the recording operation is always performed, when the surrounding temperature reaches a maximum set surrounding temperature, the recording rate corresponds to a recording rate at which the surrounding temperature does not rise, and when the temperature drops to respective set surrounding temperatures, the recording rate corresponds to their respective set recording rates.
