Abstract

Hard disk drives (HDDs) provide an important data-storage medium for computers and other data-processing systems. In most HDDs, rotating disks coated with a thin magnetic layer or recording medium are written with data that are arranged in concentric circles or tracks. Data are read or written with a read/write (R/W) head, which consists of a small horseshoe-shaped electromagnet. Figure 1.1 shows a simple illustration of a typical hard disk servo system with a voice-coil-motor (VCM) actuator.
