<p>An optical disc drive apparatus includes: a laser beam source (5); a collector device (3) disposed as facing a disc (2) adapted to record a signal, which collects a laser beam emitted from the laser beam source (5) onto the disc (2); a record processing module which records the signal on the disc (2) through the collector device (3) while modulating laser power of the laser beam source (5); a reflecting light level detecting module (4) which receives the reflecting light when the signal is recorded and detects a level of the reflecting light; a laser power control module (16) which controls the laser power when the signal is recorded based on the detected level of the reflecting light; a tilt control module (7) which controls a tilt angle between the disc and the collector device based on the detected level of the reflecting light; and a switching module which switches between control of the laser power and the tilt angle.</p> |
