摘要： An optical disk drive has a swing arm that is pivotally supported and upon which is mounted an optical head. The optical head illuminates a small laser beam spot, through an objective lens, onto an optical disk. The swing arm is rotated around a pivotable supporting assembly by a rotary motor through a gear train. One of the gears in the gear train is mounted on a tip of the arm. The arm is stably supported at two portions—one portion being the pivotable supporting assembly and the other portion being the rotary motor cooperating with the gear train. One of gears in the gear train preferably has a backlash eliminator including a plurality of associated gears, one of which is elastically suspended by a biasing element that applies a force in a constant direction. The rotary motion of the rotary motor is transferred to arm-rotation without slippage. The drive has an electromagnet, which applies a magnetic field onto the disk and is mounted a position opposite to the objective lens with respect to the disk.

摘要： 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.
