SERVO SECTOR ALLOCATION FOR HIGH SAMPLING RATE |
摘要 |
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 of servo sectors on all remaining disk surfaces. A master servo feedback signal is then derived from the surface(s) with an increased number of servo sectors and provided to a master PES controller (44). A slave servo feedback signal is derived from the surface that is being accessed and is provided to a slave PES controller (46). The master PES control signal (Xm) is then combined with the slave PES control signal (Xs) to form a single position error signal (Xe) that is used to control the positioning of a transducer (58).
