Abstract
Systems and methods for writing a sequence of data to a disk drive using sorted data zones are provided. In one embodiment, a multi-head disk drive comprises a plurality of disk surfaces, wherein each disk surface comprises a plurality of data zones, each data zone having a data transfer rate different from the other zones of the respective disk surface. The multi-head disk drive also comprises a head assembly comprising a plurality of heads, wherein each head is configured to write data to a respective one of the disk surfaces, and a controller configured to operate the plurality of heads to sequentially write a sequence of data blocks to the plurality of disk surfaces in accordance with a list of head-zone combinations ordered from highest data rate to lowest data rate, each head-zone combination corresponding to one of the heads and a data zone of the respective disk surface.
