  • Patent number: 7307838
    Abstract: A hard disc drive carrier comprises a main body, a first element extending from the main body, a second element extending from the main body opposite to the first element with a hard disc disposed between the first and second elements, at least one first pad disposed on the first element, and at least one second pad disposed on the second element. The first and second elements serve as rails for the hard disc drive carrier sliding in a hard disc drive bay. When the hard disc drive carrier reaches a predetermined position in the hard disc drive bay, the first and second pads abuts the hard disc drive bay to avoid vibration between the hard disc drive carrier and the hard disc drive bay.

  • Patent number: 6819556
    Abstract: A server system and a vibration-free extractable hard disc drive assembly thereof. The server system includes a chassis and the vibration-free hard disc drive assembly. The assembly is disposed in the chassis in an extractable manner. The vibration-free hard disc drive assembly includes a tray, a vibration-absorbing pad, and a hard disc drive. The tray is disposed in the chassis in an extractable manner. The vibration-absorbing pad is disposed on the tray. The hard disc drive is disposed on the tray via the vibration-absorbing pad. Thus, external vibration transmitted to the tray is reduced by the vibration-absorbing pad, limiting the vibration transmitted to the hard disc drive; therefore, the vibration applied to the hard disc drive is reduced.
