Abstract
An automatic gain control device includes: servo loop for performing servo control based on an error signal; gain control unit for controlling gain of the servo loop in accordance with gain control value; and storage unit for storing gain control values. The gain control unit starts gain control using the gain control value stored in the storage unit as default value with which the gain control is started, and stores the gain control value newly obtained by the gain control to the storage unit after the gain control is completed.
