摘要： PROBLEM TO BE SOLVED: To provide an optical disk device capable of shortening processing time while keeping signal quality by controlling execution of adjustment itself to omit unnecessary adjustment.
SOLUTION: The optical disk device is provided with: a first recording condition adjusting part for adjusting a recording condition parameter to be optimal with respect to an optical disk; a second recording condition adjusting part for adjusting a recording condition parameter to be optimal by using the output of a state change detection part as a trigger; an output characteristic storage part for storing the optimal recording condition parameter which is the output result of at least the first or second recording condition adjusting part; and an adjustment execution control part for controlling the execution of the recording condition parameter adjustment of each state changing time on the basis of the fluctuation amount of the optimal recording condition parameter in the state change stored in the output result storage part. A control range where the second recording condition adjustment is executed by the adjustment execution control part during each state change is made variable.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for adjusting recording and reproduction parameters which are adaptive to changes in a recording environment or a reproduction environment while shortening a recording/reproducing time including an adjustment time and preventing the deterioration of record with respect to a recording/reproducing device for recording/reproducing information by irradiating a recording medium with a laser beam. SOLUTION: The recording/reproducing time including the adjustment time can be shortened and a test recording area for the use can also be reduced by performing parameter adjustment while changing adjustment items of the recording/reproducing parameters according to changes in the recording/reproducing environments.
