Abstract

Systems and methods are disclosed for performing rewrite operations on recording bands of a data storage medium. In some embodiments, a storage device may receive a write request to be recorded to a band including a plurality of contiguous data storage areas (e.g. tracks) spanning from a first storage area to a last storage area. The device may determine a target area of the band to which to record the data, and perform a partial rewrite operation on less than all data storage areas of the band when the target area is not within a threshold number of data storage areas from the first storage area. In some embodiments, the rewrite operation may include reading data recorded in a first arrangement from the target band, modifying the data, and recording the modified data to the band in a second arrangement including a physical recording order different than the first arrangement.
