Abstract: An exemplary write method disclosed herein includes receiving a request to write data to a consecutive sequence of logical block addresses (LBAs); identifying a first non-contiguous sequence of data tracks mapped to a first portion of the consecutive sequence of LBAs; and identifying a second non-contiguous sequence of data tracks mapped to a second portion of the consecutive sequence of LBAs, where the second portion sequentially follows the first portion. The method further includes writing the data of the second portion of the consecutive sequence of LBAs to the first non-contiguous sequence of data tracks during a first pass of a transducer head through the radial zone and writing the data of the first portion of the consecutive sequence of LBAs to the second non-contiguous sequence of data tracks during a second, subsequent pass of the transducer head through the radial zone.
