Abstract
A servo system for use in a magnetic recording media is disclosed, with the system utilizing short and long address tracks in a predetermined pattern to increase the usable data storage space on the media. A special pattern is utilized following the A and B BURST patterns for each track on the disk to assist in calibration of the drive. In addition, a special pattern is provided preceding the track address portion of the sectors to identify the associated track address as being a long address, a short address or as the origin sector.
