Structural Sensitivity Analysis of Thermal Off-Track in Hard Disk Drives.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994
A study was conducted on the structural sensitivity analysis of the thermal off-track in hard disk drives. Indexes were proposed to measure the influence of the deviated thermal expansion coefficient on the off-track. These were the influence coefficient for each component, the influence coefficient for each connecting part and the regulation ...

Multiple robust track‐following controller design in hard disk drives [PDF]

International Journal of Adaptive Control and Signal Processing, 2007
AbstractThis paper presents a new technique for track‐following control in hard disk drives, in order to achieve high tracking precision of magnetic read–write headsuniformlyfor a huge number of disk drives. The basic idea in this technique is to classify the disk drives into several sets depending on dynamics properties, and to apply a robust ...

Modeling and Control of a Dual Stage Actuator Hard Disk Drive

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
A data-based approach is presented for modeling and controller design of a dual-stage servo actuator in a hard disk drive. The servo actuator in this hard disk drive consists of a conventional voice coil motor and a piezo-electrically actuated suspension.
