Identification and high bandwidth control of hard disk drive servo systems based on sampled data measurements
(2007)One of the key factors that determines the track density of a hard disk drive (HDD) is the performance characteristics of the HDD servo system, the control system that positions the READ/WRITE magnetic head close to the ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2002)Track density in hard disk drives (HDD) is related to the performance characteristics of the HDD servo control system. Higher track density can be achieved by improving the performance characteristics of the servo controller ...

Position error signal estimation at high sampling rates using data and servo sector measurements
(2003)The sampling rate in most hard disk drives (HDDs) is limited by the number of servo burst sectors that have prewritten position error signal (PES) data and by the spinning speed of the HDD. This paper presents an algorithm ...

Servo Control Design for a Hard Disk Drive Based on Estimated Head Position at High Sampling Rates
(2003)In this paper we use the ACORN estimator that generates estimates of the head position by processing servo burst and data sector measurements of the mean square error (MSE), to provide head position error measurements at ...
