Abstract

The 90nm and 15nm flying-height sliders we designed for small magnetic disk drives are based on a basic design guide we previously proposed that covers (1) a very small slider, (2) a multipad slider or side-step slider, and (3) a negative-pressure slider use in low spacing mode alone. These experimentally prototyped sliders were confirmed to fly stably on the disk at the prescribed 90nm and 15nm heights, and have been commercialized for 3.5-inch and 2.5-inch hard disk drives. These practical results demonstrate the feasibility of the proposed basic design guide.
