Abstract
A disc storage system includes a rotating disc and a transducer. The transducer is carried on a slider which is supported by an armature. The armature is used to move the slider radially across the disc surface whereby information may be read from or written to the disc surface of the transducer. The slider includes an air bearing surface which faces the disc surface. As the disc rotates, the air bearing surface causes the slider to “fly” over the disc surface. Pads are provided on the air bearing surface to improve operational characteristics of the system. For example, the pads may be used to reduce the stiction or improve flying characteristics. Flying instabilities associated with the pads are addressed by a number of characteristics provided to the air bearing surface.
