Design and performance of novel air bearing slider

Lower flying height provides higher recording density in magnetic disk drives. Therefore well-designed sliders are essential for higher recording density. In order to break the limits of conventional machined straight rail sliders, and also to make effective use of MR heads and constant density recording, a novel “Parasol” shaped slider using positive and negative pressure has been developed. This “Parasol” slider provides a constant flying height profile, stable low flying height, and debris elimination
