Patent ID: 6980386

Claim:
A data storage device comprising: a first data storage surface rotatably mounted on a spindle, wherein the first data storage surface is partitioned into a first region and a second region, each region comprising data tracks; a second data storage surface rotatably mounted on the spindle, wherein the second data storage surface is partitioned into a first region and a second region, each region comprising data tracks; wherein the first regions on each surface are approximately an equal distance on their respective surfaces from the spindle; wherein the second regions on each surface are approximately an equal distance on their respective surfaces from the spindle, the second regions being at a different distance than the first regions; an actuator assembly adjacent the first data storage surface and the second data storage surface which carries a plurality of transducers for movement of each transducer over a different data storage surface; and a control system operably programmed to write data to the first and second surfaces using the transducers to: map data to consecutive data tracks in the first region on the first surface in a first direction until an end of the first region on the first surface; then map data to consecutive data tracks in the first region on the second surface in the first direction until an end of the first region on the second surface; then map data to consecutive data tracks in the second region on the second surface in the first direction until an end of the second region on the second surface; then map data to consecutive data tracks in the second region on the first surface in the first direction.
