Abstract
Nowadays, despite the emerging adoption of the solid state drives, hard disk drives (HDDs) are still used extensively as cost-effective and reliable solutions for data storage. In addition to its usual application in desktops and laptops, HDDs become the primary storage medium for the data centers. The track following control task in HDD requires that the read/write head be positioned over the data track center at nano-scale accuracy, which requires an error tolerance about 7nm. Therefore, the dual-stage HDD is introduced to enhance the HDD control performance for extended bandwidth and improved disturbance rejection.
