  • Optical disc device and optical disc reproduction method
    Patent number: 9171564
    Abstract: An optical disc device is configured to reproduce an optical disc. The optical disc device includes an optical pickup, a high-frequency production component, a driver and a controller. The optical pickup includes a laser emission component configured to emit a laser beam, and a light receiver configured to receive returning light of the laser beam. The high-frequency production component is configured to produce a high-frequency signal. The driver is configured to produces a drive signal for driving the laser emission component by superposing the high-frequency signal produced by the high-frequency production component onto a specific drive signal. The controller is configured to control the high-frequency production component to adjust an amplitude of the high-frequency signal.
