Abstract
A hard disk drive for a computer has a base containing a stack of rotatable disks and an actuator with a set of arms that is pivotable relative to the disks. At least one magnetic head is mounted to each arm for reading information from or writing information to a respective disk. The drive also has a stationary shock support member or comb located adjacent to the outer edges of the disks and the actuator. The teeth of the comb are interposed with the disks and arms throughout the range of pivotal motion of the arms. The teeth prevent incidental contact between the disks and arms in the event of mechanical shock to the hard disk drive.
