ABSTRACT:
The slider is provided with at least one rail portion which extends between the trailing end portion and the leading end portion on one surface of the slider body. At least one magnetic transducer is provided on a line extended from the rail portion toward the trailing end of the slider body. The rail portion is provided with indented rail portions formed along the two sides and the rail surface, excluding the indented rail portions, forms the air bearing surface. The indented rail portions are formed shorter than the rail portion so that the air bearing surface continues all the way to, at least, the trailing end portion of the slider body. The width of the air bearing surfaces, which are cut into by the indented rail portions, is maintained at approximately the same dimension over the entire length of the indented rail portions. This reduces dependency of the flying height and flight attitute on the skew angle and, at the same time, prevents minute particles from the slider, generated through dry etching, from adhering to the side surfaces. Magnetic head elements are manufactured from a magnetic head aggregate which includes a section of a wafer to be formed into magnetic head elements, each magnetic head element comprising a slider body and at least one transducer, wherein the at least one transducer for each magnetic head element is formed at a trailing end of the magnetic head aggregate by fabricating a thin film element which is integrated with the slider body. A mask is placed over the magnetic head aggregate with openings through which the slider bodies are etched to form the indented rail portions. Finally, the magnetic head aggregate is machined to create the indented center portions and indented side portions, and the magnetic head aggregate is cut into plural magnetic head elements.
