ABSTRACT:
Improved apparatus and a method are disclosed for controlling the flying height of a head over a rotating medium, such as used in a rigid disk drive employing magnetic, magneto-optic or optical recording techniques. The flying height is controlled via magnetic attraction or repulsion to maintain a selected and substantially uniform flying height of the head with respect to the rotating medium.
