Abstract:
In a method for implementing track shape control during a self servo-write process, an error in a targeted path for writing servo data onto a first track of a disk is detected. The error is correlated with a second error for a targeted path in a previously written track of the disk. A correction is generated for a feed-forward signal used to position a writing element which is used to write servo data for a subsequent track of the disk.
