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.
