PURPOSE: A hard disk drive protecting a head and a disk surface is provided to prevent a contact between the head and a disk by an auxiliary load arm. CONSTITUTION: An HDD(Hard Disk Drive) is composed of a head stack assembly(1) and a disk assembly(7) in order to make heads(5,10) safely fly when a disk(6) is rotated or stopped by driving a servo motor. An auxiliary load arm(8) is mounted on the head stack assembly(1). The auxiliary load arm(8) supports the heads(5,10) when the disk(6) is stopped, and is separated from the heads(5,10) when the disk is operated.
