ABSTRACT:
An optical disk apparatus includes a spindle motor for rotating a mounted optical disk, and a swing-motion type optical head apparatus. The swing-motion type optical head apparatus scans the optical disk in a radial direction of the optical disk by moving the objective lens. The head apparatus is made to swing about a swing axis in a plane parallel to a recording surface of the mounted optical disk. The swing-motion type optical head apparatus includes an arm carrying the objective lens thereupon, and provided at the first side of the mounted optical disk. A supporting member is provided for supporting the arm so as to enable the arm to swing about the axis. Driving device are provided for causing the arm to swing. The supporting member and the driving device are provided at a location outside the optical disk when viewed in a direction perpendicular to the recording surface. The mounted optical disk has a level within a height of the supporting member and the driving device, such that the supporting member and the driving device extend from the first side of the mounted optical disk to a second, opposite side of the mounted optical disk.
