Summary:An optical disk apparatus capable of stably moving an optical head is provided. The apparatus includes an optical head for recording data to or reproducing data from a disk, a first guide member having an axis substantially parallel to the disk for supporting the optical head in such a manner that the optical head is moved along the axis, a second guide member for limiting rotation of the optical head about the axis, a rack mounted on the optical head and having a reference pitch line substantially parallel to the axis, a pinion for moving the optical head by the pinion being engaged with the rack and being rotated, and a pressing member for pressing the rack toward tie pinion. The vector of a force exerted by the pinion on the rack in response to the pressing member pressing the rack toward the pinion substantially intersects the axis.
