PURPOSE:To maintain linearity of a main magnetic pole edge and prescribed film thickness of a main magnetic pole extending over a long period, and also to execute vertical magnetic recording of high density, which is excellent in a short wavelength characterisitc, by providing a ligh hardness non-magnetic material such as an amorphous non-magnetic alloy, etc. so as to cross both base bodies, on a slide-contacting part to a recording medium of a recording and reproducing head, and forming a strong structure against peeling force. CONSTITUTION:A magnetic head is formed by a structure in which a high hardness non-magnetic material 6 is provided in a state shown by the figure on a main magnetic pole 2 consisting of a high magnetic permeability magnetic film, and a non-magnetic base body 4 consisting of a non-magnetic material such as ceramics, etc., so that influence of peeling force exerted on a moving direction (an arrow F in the figure or its opposite direction) of a recording medium (not shown in the figure) is weakened. Also, as a result of a fact that this high hardness non- magnetic material 6 is provided, an area to which the non-magnetic base body 4 is joined is increased, and joining strength of the non-magnetic base body 4 for pinch-holding and fixing the main magnetic pole 2 is also strengthened. In case when an especially hard good conductor, for instance, an amorphous non-magnetic alloy is used as the high hardness non-magnetic material 6, a new effect such that a leakage magnetic field in the track width direction is reduced is generated. |
