Pickup device and information recording apparatus

摘要

In a pickup device used for a drive apparatus of an optical disc, a storage element is provided. The storage element stores individual characteristic information associated with the pickup device. For example, the storage element stores the individual characteristic information associated with the level of the recording light waveform which is output from the LD provided in the pickup device. In recording information, the microcomputer in the drive apparatus obtains the individual characteristic information from the storage element in the pickup device and executes information recording by using an optimum write strategy determined in consideration of the individual characteristic information. Accordingly, the difference in characteristics of pickup devices is removed, and improvement and stabilization of the recording characteristic can be realized.
