Abstract: A data storage device includes one or more storage media that include multiple physical storage locations. The device also includes at least one cache memory having a logical space that includes a plurality of separately managed logical block address (LBA) ranges. Additionally, a controller is included in the device. The controller is configured to receive data extents addressed by a first LBA and a logical block count. The controller is also configured to identify at least one separately managed LBA range of the plurality of separately managed LBA ranges in the at least one cache memory based on LBAs associated with at least some of the received data extents. The controller stores the at least some of the received data extents in substantially monotonically increasing LBA order in at least one physical storage location, of the at least one cache memory, assigned to the identified at least one LBA range.

Abstract: Systems and methods are disclosed for binding shingled recording bands in data storage devices, particularly devices employing shingled magnetic recording. In one embodiment, an apparatus may comprise a controller configured to define boundaries of an area of a data storage medium based on a constraint and a list of defective sectors. In another embodiment, an apparatus may comprise a data storage device including a memory configured to store data in a shingled manner where one track partially overlaps an adjacent track, and a controller configured to define boundaries of a plurality of bands, each band including a plurality of tracks of the memory, based on the results of an error discovery scan for defective sectors of the memory.

Abstract: A method for managing data bands within an interlaced magnetic recording (IMR) architecture includes transmitting read/write characteristics of a logical block address space, the read/write characteristics including coupling information characterizing a physical arrangement of data blocks associated with different logical zones in the logical block address space, where each of the logical zones spans a continuous range of logical block addresses mapped to a series of data blocks physically interlaced with another series of data blocks corresponding to another one of the logical zones. The method further provides for executing a write command instructing a data write to a target logical zone of the logical zones, the write command being generated based on the transmitted coupling information.
