ABSTRACT:
A flying-type magnetic head has a slider having stable flying and a constant flying height and a method of manufacturing the same. A plurality of substantially parallel ground groove groups each having a positive angle with respect to the fluid inflowing direction of a slider and a plurality of substantiality parallel ground groove groups each having a negative angle are formed by cutting on a plate surface state of a material, and intersect to form the fluid lubricating surface having a rhombic shape or a truncated rhombic shape. The slider is cut out in a range including at least three of the fluid lubricating surfaces, thereby constructing a flying-type magnetic head. In this case, the fluid lubricating surface having the rhombic shape or a shape near the rhombic shape can be employed in the slider, and can also be employed in the shape where part of the rhombic shape is cut out. In the embodiment, the slider is so cut out that two fluid lubricating surfaces are disposed at the fluid inflow end, and one fluid lubricating surface at the fluid discharge end. However, the slider may be so cut out that one fluid lubricating surface is disposed at one inflowing end and two fluid lubricating surfaces are disposed at one discharge end.
