  • Patent number: 6981270
    Abstract: A plunger-latch mechanism for an optical disk drive has a plunger type solenoid, a plurality of resilient members, a connecting member, a latch, a wedge and a rotary member. While the tray is pushed into the casing, a mutual movement between the rotary member and the latch cause the latch rotate to be locked by the wedge. Since the plunger type solenoid opens the latch without resistance to the resilient force of the resilient members, the electric power required to open the latch is greatly reduced. Moreover, the locking force between the latch and the wedge is significantly increased. Therefore, the performance of the plunger-latch mechanism for optical disk drive is improved.

  • Patent number: 6862738
    Abstract: An optical compact disk drive includes a housing with a top cover, a disk-supporting tray mounted in the housing for supporting a compact disk thereon and cooperating with the top cover to define a gap therebetween, and an acoustic-and-vibration attenuator mounted in the gap to divide the gap into a plurality of angularly spaced apart compartments around a central axis that passes through a center of the compact disk.

  • Publication number: 20050039199
    Abstract: A sliding mechanism for an optical compact disk drive includes a right and left slide tracks respectively mounted at opposite sides of a tray of the optical compact disk drive. A plurality of lumpy contacts are formed on the right and left slide tracks respectively to fit with a plurality of recesses of a lower cover of the optical compact disk drive. By respectively having the lumpy contacts in point to point contact with the corresponding recesses, the tray smoothly moves forth and back in a stable manner to outmost and innermost positions. A slide body of each slide track is provided with a hook, a protection piece and a fastening piece to hold the tray at its outermost or innermost positions. Thereby, the stability and competitivity of the optical compact disk drive assembled with the sliding mechanism of the invention is increased.

  • Publication number: 20040264944
    Abstract: A fixing mechanism for use in a peripheral storage device having a cover and a core, includes a first hook slip element on the cover and a second hook slip element on the core. The first hook slip element is formed with a bending part and an extension part. The second hook slip element is formed with a first step part on which the bending part rests and a hook slip part for the extension part to pass therethrough to be engaged with the hook slip part, such that the cover and the core are hooked together in a way that movement of the cover in both vertical and horizontal directions is restricted with respect to the core.

  • Patent number: 6826768
    Abstract: An optical compact disk drive includes a housing and a mounting seat with a disk-supporting tray that has opposite front and rear peripheral portions and that is formed with a recess between the front and rear peripheral portions and an elongated opening extending from a center of the recess to the rear peripheral portion. A pair of front air-communicating openings are formed in the front peripheral portion, and at least a rear air-communicating opening is formed in the rear peripheral portion. Air is permitted to flow from a bottom side to a top side of the disk-supporting tray through the front and rear air-communicating openings.
