Abstract
There is provided an optical disk drive that pursues power saving and simultaneously assures data recording quality. A servo processor of the optical disk drive has a low frequency equalizer, a high frequency equalizer, a limiter, and an adder. A limit voltage value of the limiter is set by means of a control command from a system controller. The limit voltage value is set so as to become greater during a data recording period than in a data regeneration period. An output from the adder is supplied as a tracking drive signal to a tracking actuator or as a focus drive signal to a focus actuator.
