Recording medium driving apparatus including at least a turntable, a spindle motor, and a linear driving device

摘要

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 chassis 70 , a rotating plate 63 that is rotatably provided on the chassis 70 , a rotational center determining means 61 that determines the rotational center of the rotating plate 63 with respect to the chassis 70 , and a rotational driving means 62 for rotating the rotating plate 63 around the rotational center. At least part of the linear driving means is fixed on the rotating plate 63 and the rotation of the rotating plate 63 by the rotational driving means 62 adjusts the direction in which the head apparatus 22 is moved by the linear driving means so as to match a predetermined radial direction with respect to a rotational center axis of the turntable 26.
