Systems and Methods for Improving Disk Drive Synchronization

A method for positioning a read/write head assembly in relation to a magnetic storage medium, the method comprising:

• providing a magnetic storage medium, wherein the magnetic storage medium includes at least one track with at least a first sector and a second sector associated with the track;
• identifying the first sector;
• sampling a first information set retrieved from the first sector, wherein a subset of the first information set is stored;
• identifying the second sector;
• sampling a second information set retrieved from the second sector;
• correlating a subset of the second information set with the subset of the first information set;
• and
• combining the subset of the first information set with the subset of the second information set to yield an indication of a location of the read/write head assembly relative to the magnetic storage medium.

A head location feedback device, the device comprising:

• an interface circuit, wherein the interface circuit is operable to receive an information stream retrieved from a magnetic storage medium, wherein the magnetic storage medium includes at least one track with at least a first sector and a second sector associated with the track, and wherein the information stream includes a first burst obtained from the first sector and a second burst obtained from the second sector;
• and
• a multiple sector error detection circuit, wherein the multiple sector error correction circuit is operable to:
• phase align the first burst with the second burst;
• determine a first amplitude of the first burst;
• determine a second amplitude of the second burst;
• and combine the amplitude of the first burst with the amplitude of the second burst, wherein the combination of the amplitude of the first burst and the amplitude of the second burst corresponds to a position error of a head assembly relative to the magnetic storage medium.
