ABSTRACT:
A hard disk drive includes a housing having a base plate and a cover plate, and a spindle motor installed on the base plate. At least one magnetic disk to store data is installed at the spindle motor and rotated by the spindle motor. An actuator is pivotably installed on the base plate and has a magnetic head to record data on the magnetic disk and to reproduce the data from the magnetic disk. At least one disk protector protrudes to a predetermined height toward the magnetic disk at a position corresponding to an edge portion of the magnetic disk where data is not recorded. A magnetic head protector protrudes to a predetermined height toward a suspension in a parking zone where the magnetic head is parked. The disk protector and the magnetic head protector are provided on an upper surface of the base plate and/or a lower surface of the cover plate. Thus, when an external impact is applied to the hard disk drive, the magnetic disk and the magnetic head are prevented from being damaged.
