Abstract
A disk drive system is disclosed. The disk drive system includes at least one substantially flat magnetic disk, at least one read/write head, at least one head stack assembly, and at least one axial positioning device. Each head stack assembly is coupled to at least one read/write head, which is suspended in proximity to a magnetic disk for reading data from and writing data to the magnetic disk. Each axial positioning device is coupled to at least one head stack assembly for variably positioning the head stack assembly in a direction substantially normal to the disk surfaces. By axial positioning of the head stack assembly, each read/write head can be loaded onto a magnetic disk by being suspended in close proximity to the magnetic disk at the flying height of the read/write head, or unloaded from the magnetic disk by being suspended at a height in relation to the magnetic disk greater than the flying height.
