Abstract:
1. A recording medium driving apparatus including at least a turntable for rotationally driving a recording medium that has been mounted, a spindle motor for driving the turntable, a head apparatus for performing recording and/or reproduction for the recording medium, and linear driving means for moving the head apparatus in a straight line, the recording medium driving apparatus comprising: a chassis; a rotating plate that is rotatably disposed on the chassis; rotational center determining means for determining a rotational center of the rotating plate with respect to the chassis; and rotational driving means for driving the rotating plate around the rotational center; wherein at least part of the linear driving means is fixed to the rotating plate, and the rotational driving means rotates the rotating plate so that a direction in which the head apparatus is moved by the linear driving means is adjusted to match a predetermined radial direction with respect to a rotational center axis of the turntable; wherein the rotational driving means is composed of an eccentric pin that is attached to the chassis so as to be free to rotate and a long hole that is provided in the rotating plate; and wherein the eccentric pin rotates in a state where the eccentric pin abuts the long hole so that the rotating plate is rotated by a desired angle.
