METHOD FOR DRIVING OPTICAL PICKUP, OPTICAL PICKUP, AND OPTICAL DISK APPARATUS

摘要

PROBLEM TO BE SOLVED: To make an optical pickup simplifiable and miniaturizable and to make preventable various kinds of deterioration in the characteristics by applying to the case in which an aberration correcting mechanism is constituted of a liquid crystal, for example, which relates to a method of driving optical pickup, an optical pickup, an optical disk apparatus. SOLUTION: Driving signals S0 and S3 for an actuator and driving signals S1 and S3 for the aberration correction mechanism 16 are multiplexed and transmitted.
