Abstract
A magnetic recording system includes a patterned medium comprised of land areas and trough areas, a write element which writes the data to the patterned medium, and a read element which reads the data from the patterned medium and servo information from the troughs. The land areas store data and the trough areas inhibit storage of data. The read element is wider than the write element.
Claims19
A magnetic recording system comprising:
- a patterned medium comprised of land areas and trough areas, the land areas for storing data and the trough areas for inhibiting storage of data;
- a write element which writes the data to the patterned medium;
- and
- a read element which reads the data from the patterned medium, the read element being wider than the write element.

An apparatus comprising:
- storing means for storing data magnetically in data tracks, the data tracks being separated by erase bands that are physically stamped onto the storing means;
- writing means for writing data to the storing means;
- and
- reading means for reading data from the storing means, the reading means having a width that is greater than a width of the writing means.

A method of accessing data, comprising:
- moving a recording head over a patterned medium comprised of land areas and trough areas, the land areas storing data and the trough areas storing servo information;
- transferring data on a land area;
- reading servo information from trough areas at the same time as transferring the data;
- and
- using the servo information to move the recording head relative to the land area.
