Abstract
A self-loading slider for a magnetic head assembly is formed with an air bearing surface having spaced rails and a negative pressure region between the rails. Shallow recesses or reliefs are formed in the rails so that ambient pressure is substantially maintained in the areas of such recesses along the rails. The slider is relatively insensitive to skew and disk curvature due to flutter or static deformation.
