摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Systems and methods are disclosed for performing a rewrite operation on recording bands of a data storage medium. In some embodiments, data may be read from a target band including a plurality of tracks, and modified. A portion less than all of the modified data is stored to a nonvolatile memory, and all of the modified data is written to the target band. In some embodiments, modified data corresponding to the first two tracks of the target band is stored to the nonvolatile memory, and modified data corresponding to the third track of the target band is written back to the first physical track. Each track may be written in order, ending with the modified data corresponding to the first two tracks. The result may be that data for each track in the band has shifted up two tracks, with data for the first two tracks moved to the end.
