A retract control method of an HDD to prevent a head from landing on a disk due to a retract failure and an HDD using the same. The retract control method includes performing a retract operation of retracting a head on the ramp, determining whether the head is normally retracted on the ramp, when it is determined that the head is not normally retracted on the ramp, moving the head to a predetermined zone of a disk, and when the head arrives at the predetermined zone of the disk, parking the head in the predetermined zone of the disk by stopping a spindle motor. Accordingly, even when a retract operation fails, a reliable retract operation can be performed by retrying the retract operation while adjusting one or more retract parameters.
