In one embodiment, a device may comprise a data storage medium including a first band and a processor. The first band may include a plurality of tracks storing data in a shingled manner where a first track at least partially overlaps a second track. The processor may be configured to receive a write command directed to the first band, increment a first rewrite count of the first band based on the write command, and when the first rewrite count exceeds a first rewrite threshold, perform a read-modify-write (RMW) operation for all of the first band. In some embodiments, a device may maintain write counts for sections of a band, and perform RMW operations on less than all of the band.

Abstract: In a shingled magnetic recording system, LBA can be dynamically allocated to an un-shingled media partition (UMP) based on a usage metric. In one implementation, the usage metric depends upon the frequency of writes to storage region and/or upon how recently the storage location has been written to. Data corresponding to one or more LBA ranges within a shingled data region may be rewritten to a storage region within a UMP on the disk.
