Abstract
In a particular embodiment, a storage system is disclosed that includes a discrete track media having a plurality of concentric data tracks to store data and including a respective plurality of non-magnetic regions to separate adjacent data tracks. The non-magnetic regions include encoded position information. The storage system further includes a controller adapted to adjust a position of a read/write head relative to a center of a particular track based on the encoded position information.
Claims21
A storage system comprising:
- a discrete track media including a plurality of concentric data tracks to store data and including a respective plurality of non-magnetic regions to separate adjacent data tracks, the non-magnetic regions including encoded position information;
- and
- a controller adapted to adjust a position of a read/write head relative to a center of a particular track based on the encoded position information.
A method comprising:
- detecting first and second position information encoded at first and second grooves adjacent to a particular data track of a discrete track media;
- determining a position error of a read/write head relative to a center of the particular data track based on the first and second position information;
- and
- adjusting the position of a read/write head toward the center of the particular data track based on the determined position error.
A recording medium comprising:
- a plurality of patterned data tracks to store data;
- a respective plurality of non-magnetic regions to store servo position information that can be used to determine a servo position error;
- wherein each data track of the plurality of patterned data tracks is separated from adjacent data tracks by at least one non-magnetic region.
