Classification: CPC G | IPC G  H

Claim 20:
21. A data storage device, comprising:
a storage medium comprising a plurality of data tracks;
a channel circuit configured to:
receive a read signal for a first data track of the plurality of data tracks, wherein the first data track includes a first plurality of data sectors;
receive a read signal for a second data track of the plurality of data tracks, wherein:
the second data track includes a second plurality of data sectors;
the second data track is different than the first data track; and
the read signal for the second data track is received after the read signal for the first data track;

process, during a first track read operation period, the first plurality of data sectors using error correction codes; and
process, during a second track read operation period following the first track read operation period, the second plurality of data sectors and a portion of the first plurality of data sectors using the error correction codes; and

a servo controller configured to controllably position a read head over the plurality of data tracks on the storage medium, wherein:
the plurality of data tracks is configured as continuous data tracks having a track length shorter than an integer number of revolutions; and
the channel circuit is further configured to selectively cause the servo controller to skew the read head to maintain the read head on a prior data track for a next revolution for additional processing time.
