  • Performance and power management for rotating data storage device
    Patent number: 9075538
    Abstract: A data storage device may generally be directed to a buffer that stores a plurality of command requests pending for a data storage medium and a processor that is configured to skip a first command request and execute a second command request in response to the second command request having an access latency within a first predetermined performance impact range and a power consumption within a second predetermined power savings range compared to the first command request.
    Type: Grant

  • Physical zone table for use with surface-based serpentine format
    Patent number: 7035961
    Abstract: A system and method for accessing data stored on surfaces of discs in a disc drive utilizing more than one serpent per recording zone. The serpents are traversed using a defect descriptor table and one or more physical zone tables (PZTs). An Address Translation Logic Unit is configurable to use one or more PZTs to access multiple serpents per recording zone.

  • Connector having a cable that is relatively moveable about an axis
    Patent number: 6644999
    Abstract: The invention includes a cable assembly housing. The cable assembly housing may include a main shell that defines a first cavity. The main shell may have a collar. The cable assembly may also include a cable shell that defines a second cavity. The cable shell may have a neck disposed between a mating surface and a flange. The flange of the cable shell may be disposed through the collar and inside the first cavity.

  • Connector having a cable that is relatively moveable about an axis
    Patent number: 6475021
    Abstract: Cable assembly housing. The invention includes a cable assembly housing. The cable assembly housing may include a main shell that defines a first cavity. The main shell may have a collar. The cable assembly may also include a cable shell that defines a second cavity. The cable shell may have three necks, two of which are disposed inside the first cavity, and the third neck is extended outside the collar. The cable shell may rotate about an axis of the main shell such that the cable shell is set at a predetermined angle and position with respect to the main shell.
