ABSTRACT:
A disk drive for recording data to or reproducing data from a disk includes a head for writing the data into or reading the data out of the disk by sliding on the disk or gliding over the disk. An arm member holds the head which is supported by an elastic member so that the arm member can be raised or lowered. A load force is exerted on a first position of the arm member by a so as to place the head on the disk or to make the head approach the disk. An unload force is exerted on a second position of the arm member so as to separate the head from the disk. The second position is more distant from the head than the first position from the head in a longitudinal direction of the arm member.
