Abstract:
An optical disc device is configured to reproduce an optical disc. The optical disc device includes an optical pickup and a driver. The optical pickup has a laser irradiation component that is configured to emit a laser beam to the optical disc for obtaining a return light. The driver is configured to generate a drive signal for driving the laser irradiation component based on a high-frequency signal. The driver is further configured to set an amplitude of the high-frequency signal used while reproducing a test region of the optical disc to be different from an amplitude of the high-frequency signal used while reproducing a data region of the optical disc. The test region of the optical disc is reproduced to acquire a setting signal for a setup of the optical pickup.
