Provided is an optical disc device and others capable of performing stable eccentricity correction. The optical disc device includes: a disc motor (20) driving an optical disc (1) to rotate; a rotation phase detector (21) for detecting its rotation phase; an optical head (10) having a light collection lens (13) and an LE signal generator (30) for collecting optical beams; a photo detector (16) for detecting a position of the light collection lens (13) in the optical head (10) as a position signal; an LE signal memory recorder (31) and an LE signal memory (33) for storing the position signal from the LE signal generator (30) with synchronization with the rotation phase detected by the rotation phase detector (21); an LE signal memory reproducer (32) for outputting the already detected position signal with synchronization with the rotation phase to be detected, as a correction signal; a subtractor (35); an LE signal filter (37), a drive circuit (73), and a Tk actuator (15) for moving the light collection lens (13) by using the signal from the subtractor (35); and a low pass filter (36) for reducing a high-frequency component in the correction signal.
