Patent ID: 8537489

Claim:
A method for writing servo wedge code to a disk, comprising: determining a first selected burst demodulation window; using a processor to compute a final radial head position based at least in part on the first selected burst demodulation window, wherein: (1) the final radial head position is computed based at least in part on both the first selected burst demodulation window and a second selected burst demodulation window; (2) the first selected burst demodulation window and the second selected burst demodulation window are associated with a first spiral burst amplitude and a second spiral burst amplitude, respectively, and the first spiral burst amplitude and the second spiral burst amplitude are adjacent to a central burst value; and (3) the final radial head position is further computed at least in part by computing the difference between the first spiral burst amplitude and the central burst value; and writing servo wedge code to a disk based at least in part on the final radial head position.
