Patent ID: 7787208

Claim:
A bit patterned medium comprising: a substrate; and a recording layer comprised of a plurality of bit cells which are formed on the substrate by being magnetically separated from each other, wherein a surface of the recording layer is divided into a data area and a servo area, wherein the data area comprises a super-track comprised of a plurality of sub-tracks, wherein bit cells formed on a sub-track from among the plurality of sub-tracks in the super-track are disposed so as to deviate from bit cells formed on another sub-track from among the plurality of sub-tracks in the super-track, wherein the servo area comprises a track identification (ID) including an information identifying the super-track, and a servo burst including an information of a position error signal for tracking the super-track, and wherein the servo burst comprises a plurality of bursts which are formed deviating from each other in a crosstrack direction, along a center line of the super track.
