  • Data storage device self-configuring based on customer prediction model
    Patent number: 11543981
    Abstract: A data storage device is disclosed comprising a non-volatile storage medium (NVSM), and control circuitry configured to receive a plurality of access commands, process the plurality of access commands using a customer prediction model to predict a customer of the data storage device, wherein the customer prediction model is trained off-line based on access patterns of a plurality of different customers. The control circuitry then configures access to the NVSM based on the predicted customer.
    Type: Grant

  • Data storage device bank writing servo sectors for interleaved servo control processing
    Patent number: 10783911
    Abstract: A data storage device is disclosed comprising a first head actuated over a first disk surface, and a second head actuated over a second disk surface. During a first revolution of the disk surfaces, a first set of servo sectors are written to the first disk surface and a second set of servo sectors are written to the second disk surface, wherein the first set of servo sectors are circumferentially offset from the second set of servo sectors. During a second revolution of the disk surfaces, at least one of the servo sectors in the first set is read from the first disk surface and at least one of the servo sectors in the second set is read from the second disk surface to control a position of the first head over the first disk surface.
