Abstract
An air bearing slider used with a thin film magnetic head is formed with a corner recess and a taper at the leading edge. The taper is disposed between the corner recess and one side of the slider. A central polygon-shaped recess is bounded by pads which are joined by a connecting section. In an alternative embodiment, a recess at the leading edge separates the taper into sections. In another embodiment, a second corner recess is provided at the leading edge and the taper is disposed between the first and second corner recesses. The shaped recesses and tapers improve the flying characteristics of the slider and enhance air bearing stiffness. A single etch process is used to form the recesses and side reliefs of the slider.
