Optical disk apparatus having a reduced size.

摘要

An optical disk apparatus characterized in that the apparatus comprises: a spindle motor (14) for rotating a mounted optical disk (17); and a swing-motion type optical head apparatus (15) for scanning the optical disk in a radial direction of the optical disk by moving the objective lens (50), the head apparatus being made to swing about a swing axis in a plane parallel to a recording surface (17a) of the mounted optical disk (17), the swing-motion type optical head apparatus comprising: a head main body (20) supported by bearing device (23) so as to be enabled to swing about the axis; and an electromagnetic driving device (40) for driving the head main body to swing, wherein the bearing device and the electromagnetic driving device are provided at a location outside of the mounted optical disk when viewed in a direction perpendicular to the recording surface, so that the mounted optical disk has a level within the height of the bearing device (23) and the electromagnetic driving device (40). <IMAGE>
