  • Publication number: 20220375701
    Abstract: A movement mechanism includes: a case; a moving portion movable with respect to the case; and a support member that links the case and moving portion together and supports the moving portion so as to be movable with respect to the case. The support member has a plurality of pairs of first support portions and a plurality of pairs of second support portions, each of which is elastically deformable, has a plate-like shape, and extends between the case and the moving portion. The first support portions and second support portions are respectively placed on a first side and a second side in a moving direction of the moving portion so as to be symmetric with respect to the moving portion in plan view.

  • Patent number: 5887128
    Abstract: A redundant disk storage system having data stored on one disk and identical data on second disk, wherein the data stored on the second disk is in a different radial location determined by an offset. The offset could be such that the data on the first disk is stored near the inner circumference and the identical data is stored on the second disk near the outer circumference. Moreover, a RAM associated with each disk drive which stores the address and offset eliminates a RAM in the main disk controller.
