Abstract

The paper presents a novel approach for driving a Voice Coil Motor (VCM) in a Hard Disk Drive (HDD), based on an adaptive voltage driver. The adaptation of the driver compensates for the variations of VCM resistance and is performed either during seek operations and track following. As a result, the performance of the proposed driver matches closely that of a standard current driver.
