    Abstract: A disc data storage medium can include a shingled band of tracks, some of which do not map to host accessible logical block address. The tracks that do not map to host accessible logical block addresses (cache tracks) can store cache data and may map to disc accessible logical block addresses. Data operations can be performed on the data in the cache tracks, and the data may then be moved to storage regions mapped to host logical block addresses.

    Abstract: A method includes generating a map for a storage tier. The map maps a plurality of extents to physical locations on the storage tier and is implemented as a tree with each extent to physical location mapping being one of a plurality of leaf extent nodes of the tree. Individual ones of the plurality of leaf extent nodes are compressed into small extent nodes. Different groups of the small extent nodes are associated with carrier nodes. A command that involves an extent of the plurality of extents, which is represented by a small extent node in one of the carrier nodes, is received from a host. A decompression operation is performed on the small extent node in the carrier node to provide a leaf extent node for the extent associated with the host command. An extent node operation is performed on the leaf extent node for the extent.

    Abstract: A method or system comprises determining an end data track of a write operation in response to a request for the write operation in a media storage device, saving data from an adjacent track following the end data track to a cache, performing the write operation. In one implementation, performing the write operation is comprises writing data to a plurality of data tracks in a band.
