Abstract :
Power processing technology has traditionally played a relatively small role in hard disk drive design due to a lack of necessity, and concern over electromagnetic interference with sensitive drive electronics. As data-access speeds increase, more efficient means of controlling spindle and actuator motors are required. An overview of power-related issues in disk drives is presented, and some of the ways that power processing technology can help in improving performance and power efficiency are discussed
