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 and texturing is provided to a landing zone region on the disc surface.
