ABSTRACT:
A recording medium driving apparatus can adjust the position of a linear driving means with respect to a turntable with high precision, so that a direction in which the head apparatus is moved by the linear driving means matches a predetermined radial direction with respect to a rotational center axis of the turntable. The recording medium driving apparatus includes a chassis70, a rotating plate63that is rotatably provided on the chassis70, a rotational center determining means61that determines the rotational center of the rotating plate63with respect to the chassis70, and a rotational driving means62for rotating the rotating plate63around the rotational center. At least part of the linear driving means is fixed on the rotating plate63and the rotation of the rotating plate63by the rotational driving means62adjusts the direction in which the head apparatus22is moved by the linear driving means so as to match a predetermined radial direction with respect to a rotational center axis of the turntable26.
