    Abstract: Systems and methods are disclosed for performing band rewrites on shingled storage media based on error scan counts. 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: Systems and methods are disclosed for dynamic band boundaries in data storage devices, particularly devices employing shingled magnetic recording. Band boundaries may be modified to include spare sectors from guard areas between bands to achieve field defect-slipping. Band boundaries can also be shifted to migrate spare sectors from one guard area to another in order to dynamically distribute spare sectors. In one embodiment, an apparatus may comprise a data storage medium and a controller. The data storage medium may have a first and second sequence of circumferentially adjacent data sectors, and a first guard area disposed between the first and second sequence such that no sector of the first sequence is directly adjacent to a sector of the second sequence. The controller may be configured to restructure the first sequence to include a sector from the first guard area to produce a shifted first sequence.
