ABSTRACT:
An optical disk apparatus in which a head is accommodated in a movable part which moves the head along a guide shaft in a radial direction of an optical disk. The guide shaft is engageable with the movable part and extends in the radial direction of the optical disk. The optical disk apparatus has a guide shaft compression mechanism which applies a compression force toward the movable part, which force is distributed, approximately uniformly, along the radial direction of the optical disk, to the guide shaft so that the movable part can be properly engaged with the guide shaft so as to move smoothly and stably along the guide shaft in the radial direction of the optical disk.
