  • Patent number: 10108343
    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.

  • Publication number: 20180088833
    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.

  • Publication number: 20180046382
    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.

  • Patent number: 9865296
    Abstract: A storage device performs a background operation involving seeking a read/write head between inner and outer diameters of a disk of the storage device. During the seeking, adjacent test tracks are written at a diameter between the inner and outer diameters of the disk. The adjacent test tracks are written using varying levels of laser power applied to the disk via the read/write head. An optimum value of the laser power is determined based on reading at least one of the adjacent test tracks.

  • Publication number: 20170270249
    Abstract: A health record system is described that utilizes a data transfer methodology for transmitting and storing medical test results of patients of a health clinic that avoids the use of complex IT environments. The health record system performs medical tests using medical instrumentation devices located at a health clinic that lacks connectivity to a network. The results of the medical test are printed in the form of a visual code that is non-human readable. A client device scans the visual code and the results of the medical test are extracted from the visual code and sent to a cloud environment for storage when the client device has network connectivity.
