Abstract:
An optical disc apparatus of the present invention includes an optical head (103) including a lens disposed at a position shifted from a traverse axis in a tangential direction, a traverse motor (104) as a second moving unit that moves the optical head (103) in a direction traversing tracks of the optical disc (101), a number-of-tracks calculating part (123) that calculates, as the number of tracks to be sought, the number of tracks that the optical head will traverse when moving from a first address to a second address of the optical disc (101), a tracking-drive-signal-at-seek generating part (112) and a traverse-drive-signal-at-seek generating part (119) as seek controlling units that move a convergent point of an optical beam from the first address to the second address, and a number-of-tracks correcting part (124) that corrects the number of tracks to be sought according to a shift amount of the lens from the traverse axis.
