Abstract
An optical disk unit for recording or reproducing information contained on an optical disk, wherein the optical head is mounted on a base that slides freely along a seek shaft. There is a clearance in the structure where the head base holds the seek shaft that allows for sliding of the head base with respect to the seek shaft. Wobbling of the head base during movement along the seek shaft, caused by the clearance around the seek haft, is reduced by a pressing portion mounted on the head base which presses against the seek shaft.
