ABSTRACT:
An improved disc drive is capable of compensating the relative positional shift of a head caused mainly by a temperature change. The disc drive includes a frame having a disc holder for rotatably driving a disc, a head for reading information recorded in the disc, a head carriage which is movable in a predetermined radial direction of the disc, a rotation shaft extending in parallel with the radial direction, a driving mechanism for moving the head carriage in the radial direction by engaging with the rotation shaft, an adjustment mechanism for compensating the positional shift of the head due to a change of ambient temperature by providing an additional deformation of the adjustment mechanism to the carriage.
