Abstract: Zones of a magnetic recording medium are allocated as a respective plurality of distributed media caches arranged in in a predetermined order. For each of a plurality of caching events, cache data is written to one or more of the distributed media caches. A next of the media caches in the predetermined order is selected for the next caching event if the selected caches are not a last in the predetermined order. Otherwise a first media cache is selected in the predetermined order.

Abstract: The disclosure is related to systems and methods of providing superparity protection to data. A storage device or other processing system, such as a host, may be capable of providing intermediate superparity protection to data. For example, superparity may be determined in response to a command received at a storage device. A superparity can be determined for read data to provide superparity protection to the read data. It may also be determined whether the read data is already protected by a valid superparity.
