Abstract
Reduced bit number wedge identification techniques for use within a rotating media storage device (RMSD) are disclosed. The RMSD includes a disk having a circumferential track that includes a plurality of embedded servo wedges utilized in track following. A substantial majority of the plurality of wedges include a reduced bit wedge ID field that does not have a sufficient number of bits to uniquely identify the wedge within the track. A combined wedge ID code is formed from reading at least first and second reduced bit wedge ID numbers from first and second wedges, respectively, which is used to uniquely identifying a wedge.
