  • Patent number: 8760798
    Abstract: In a storage device provided with a plurality of recording devices, the vibrations which propagate to the recording devices through a board can be reduced with a small number of parts. A storage device equipped with a plurality of recording devices having: a canister equipped with the recording device; a board equipped with a circuit that transmits a signal to the recording device or processes a signal; a chassis equipped with the board and the canister; a plate-like piezoelectric element attached to part of the board; a vibration detection sensor attached to part of the board; and a control unit that controls a drive signal given to the piezoelectric element in accordance with a sensor output of the vibration detection sensor is proposed.
    Type: Grant

  • Patent number: 8611082
    Abstract: A storage device having a plurality of recording devices in which a decrease in vibrations from the recording devices can be achieved with a small number of parts. A storage device having a plurality of recording devices mounted therein includes a handle for inserting and withdrawing the recording device into and out of the storage device. Two holding members each include a mounting portion where the recording device is mounted and a frame extending from the mounting portion to the handle. Two protrusions are formed to extend inwardly of a region surrounded by the recording device, the handle, and the two frames. A restriction plate is disposed so as to overlap the respective surfaces of the two protrusions; and a viscoelastic body is disposed at the overlapping portion for joining the two protrusions and the restriction plate to one another.
