ABSTRACT:
In an optical disk apparatus, when a focus deviation occurs, amplitude driving of a pickup is performed for focus pull-in immediately without a waiting time. The amplitude driving is performed with a first amplitude a given number of times, and when detection of a focusing point fails, amplitude driving with a second amplitude larger than the first amplitude is performed.
