    Abstract: A method includes calculating, by a data storage device processor, at least one access trajectory from a first disc surface location to at least one second disc surface location at which at least one primary data access operation is to be carried out. The method also includes determining, by the data storage device controller, whether an opportunity to commence at least one secondary data access operation exists along or proximate to the at least one access trajectory from the first disc surface location to the at least one second disc surface location.

    Abstract: Systems and methods are disclosed for employing a media read cache in a storage device. In certain embodiments, an, an apparatus may comprise a data storage drive including a volatile read cache, and a disc memory including a primary data storage region of the storage device configured for long-term storage of data via persistent logical block address to physical block address mapping, and a media read cache region configured to store a copy of data from the volatile read cache. The data storage drive may be configured to perform a read operation including: retrieve read data from the volatile read cache based on determining that the read data is available in the volatile read cache, and retrieve the read data from the media read cache based on determining that the read data is not available in the volatile read cache and is available in the media read cache.

    Abstract: A method includes writing first data on a first track of a data storage surface, and storing information for the first data in a memory other than the data storage surface. The method also includes performing a write operation on a second track of the data storage surface after the data is written on the first track. The second track is adjacent to the first track. The method further includes identifying potentially-overwritten sectors of the first track as a result of the performance of the write operation on the second track, and performing a first read operation on the identified potentially-overwritten sectors of the first track after completion of the write operation on the second track. Second data associated with the identified potentially-overwritten sectors is then stored in a solid-state memory, and mirrored to media.

    Abstract: Methods and apparatus for allocating logical sectors and bands to store data on interlaced magnetic recording tracks. The systems and methods include formatting a data storage medium to include a plurality of bands, each band of the plurality of bands including a plurality of tracks, the plurality of tracks including a subset of top tracks interlaced with a subset of bottom tracks, and each track of the plurality of tracks including a number of sectors, formatting a first band of the plurality of bands, determining an isolation region of the first band, and formatting a second band of the plurality of bands responsive to determining the isolation region of the first band.

    Abstract: An implementation of a system disclosed herein provides a method for managing data streams of sequential nature, wherein the method provides for determining that a sequence of incoming write commands are associated with an LBA range mapped to a source band and writing data of the incoming write commands to physical blocks of a destination band assigned to the LBA range of the source band such that the data of the incoming write commands is written according to a sequential order of data receipt and in a forward write direction to sequentially fill physically-consecutive blocks in the destination band.

    Abstract: Implementations disclosed herein provide for increasing storage drive performance by reserving a region of user-writeable storage space on a storage medium for overprovisioning uses, including performance-enhancing functions. Until a capacity condition of the storage drive is satisfied, write operations targeting the reserved region are written to another equal-sized region that does not contain user data.
