Abstract
Systems and methods for writing a sequence of data to a disk drive using sorted data zones are provided. One embodiment includes a disk drive comprising one or more disks having a plurality of disk surfaces, wherein each disk surface comprises a plurality of data zones, each data zone having a data transfer rate; 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 an order of head-zone combinations ordered from highest data transfer rate to lowest data transfer rate, each head-zone combination corresponding to one of the heads and one of the data zones of the respective disk surface.
