Abstract
A hard disk drive that can suppress an increase of fluttering and power consumption at high rotation speed by increasing the seek speed of a magnetic head is disclosed. An enclosure case has a 3.5 inch form factor, and a magnetic disk has an outer diameter of, for example, 84 mm. A center of the magnetic disk is shifted from a center of the enclosure case in the width direction. Owing to this, by designing a larger voice coil, it is possible to increase the driving speed of the actuator.
