    Abstract: The technology disclosed herein pertains to a system and method for storing data on a storage media using both down-track super parity and cross-track super parity. Specifically, a method disclosed herein provides for generating down-track super parity values for data on the plurality of tracks and storing the down-track super parity values on a down-track super parity row of the storage block and generating cross-track super parity values for data on the plurality of rows and storing the cross-track super parity values on a cross-track upper parity track, wherein the cross-track super parity value for any given row is generated by inputting the data on the given row into an exclusive-OR (XOR) gate.

    Abstract: A method includes receiving at a storage device a command from a host. When learning is active on the storage device, an initial parameter value of a plurality of parameter values is used for performing a first action of a plurality of actions for the command. The first action is performed using the initial parameter value of the plurality of parameter values for the command The first parameter value is incremented to a next parameter value of the plurality of parameter values for the command for use in reperforming the first action.

    Abstract: Apparatus and method for managing data in a hybrid data storage device. In some embodiments, a hybrid data storage device operates in a normal mode in which data transfer commands received from a host device are serviced by a top level controller circuit which directs a first subset of the received data transfer commands to a non-volatile rotatable recording memory and a second subset of the received data transfer commands are directed to a non-volatile solid-state memory. The controller circuit transitions to a performance mode responsive to a detected first parameter so that subsequently received data transfer commands are directed exclusively to the solid-state memory. The controller circuit terminates the performance mode and resumes the normal mode responsive to a detected second parameter.

    Abstract: A method includes storing a data group in a first zone of a plurality of radial zones of a data storage disc. Each different one of the plurality of zones has a different throughput level. The method further includes obtaining information related to an access frequency of the data group stored in the first zone of the plurality of zones. Based on the information related to the access frequency of the data group and the different throughput levels of the different zones, a determination is made as to whether to migrate the data group from the first zone of the plurality of zones to a second zone of the plurality of zones.

    Abstract: Systems and methods for maximizing shingled magnetic recording (SMR) drive capacity are described. In one embodiment, the SMR drive may include a main store to store user-accessible data, a media cache and media scratchpad to store internal data temporarily for internal operations, and a storage controller to process read and write requests. In some cases, the main store comprises a shingled media partition and an unshingled media partition. The storage controller may designate one or more data tracks from the shingled media partition as temporary data track guard bands. In some embodiments, a track range is selected based at least in part on at least one of an amount of data in the media cache, a size of the new data in the media cache, and an association between the new data in the media cache and data currently stored within the selected track range.

    Abstract: A hard disk drive includes a base deck, a motor coupled to the base deck, a magnetic recording medium coupled to the motor and having a first zone and a second zone, and a controller. The controller is programmed to cause the motor to rotate at either a first speed or a second speed when data is to be read from the first zone and to cause the motor to rotate at the first speed when data is to be written to the first zone and the second zone.
