Abstract
A servo sector allocation scheme for a disk based data storage system is disclosed that realizes an increased servo sampling rate without an associated increase in overhead. The scheme involves increasing the number of servo sectors on a subset (preferable one) of the disk surfaces in the disk drive while reducing the number on all remaining disk surfaces. A master servo feedback signal is then derived from the highly populated surface(s) and a slave servo feedback signal is derived from the surface that is being accessed. The master and slave servo feedback signals are then combined to form a single position error signal that is used to control the positioning of an appropriate transducer.
