Abstract:
A method of writing a set of servo tracks (x) each having a number of servo wedges on a plurality of disk surfaces wherein the corresponding servo wedges on each of the plurality of disk surfaces comprise a servo wedge set (z), the method comprising:(i) for a servo track set (x) writing a subset (y) comprising a plurality of servo wedges of a servo wedge set (z) on a subset of the disk surfaces such that the subset (y) is being written at one time; (ii) upon completion of act (i) writing the next subset (y) of the servo wedge set (z) on the next subset of disk surfaces such that the next subset (y) is being written at one time; (iii) repeating, if necessary, acts (i) and (ii) until all of the servo wedges of the servo wedge set (z) have been written; (iv) following act (iii) moving to a next servo wedge set (z); (v) following act (iv) repeating acts (i) through (iii) until all of the servo wedges of the next servo wedge set (z) have been written; (vi) repeating, if necessary, acts (iv) and (v) until all of the servo wedge sets (z) of the servo track set (x) have been written; (vii) following act (vi) moving to the next servo track set (x) (viii) repeating acts (i) through (vi) for the next servo track set (x); and (ix) repeating acts (vii) through (viii) for each servo track set (x).
