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 ...

Tracking Actuator for Magneto-optical Disk Drives.
Journal of the Japan Society for Precision Engineering, 1992 This paper describes the development of the tracking actuator for high-speed magneto-optical disk drives. The rotating mirror tracking actuator suspended by a single leaf spring is adopted. The actuator is required to have a fine mechanical vibration characteristics, which enables precise control against the high speed rotation of disks for high speed ...

Accurate Runout Measurement for HDD Spinning Motors and Disks
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 As hard disk drive (HDD) areal density increases, its track width becomes smaller and smaller and so is non-repeatable runout. HDD industry needs more accurate and better resolution runout measurements of spinning spindle motors and media platters in ...
