Magnetic head for reading from and writing to a rotated magnetic disc in an elevated state produced by air flow and structure for supporting same

摘要

A slider of a magnetic head is provided with first and second magnetic head parts, and a central groove so that first and second air bearing surfaces separate from each other are formed. An air flow produced between the air bearing surfaces, and a magnetic disk creates an elevating force. A width of the first air bearing surface at the leading edge is controlled to be larger than a width at the trailing edge.
