coil (VCM) that controls the head, and a ramp where the head is retracted. The storagedevice detects a current used for speed control during unloading of the head, anddetermines whether the current exceeds a predetermined value. The storage devicedetects a head position where the current exceeds a predetermined value as a rampposition, stores the ramp position, and unloads the head based on the ramp position.
