TRACK OFFEST CORRECTION AND GAIN ADJUSTMENT IN A DISK DRIVE SERVO USING STORED CORRECTION VALUES

摘要

Disk drive arrangement with servo-mechanism for controlling (thin-film) head position, etc.; the servo having a disk face (DSF1, DSF2) dedicated to servo tracks, rendered in "Quad" code (P1-P4), with special timing indicia (S1-S6) to separate position indicia. A feature is a technique for deriving and using "offset" values for an array of servo tracks.
