ABSTRACT:
A magnetic head has a magnetic core structured so that soft magnetic thin films and insulating thin films are stacked alternately. In each layer of the soft magnetic thin films, the thickness of the vicinity of a gap portion is made smaller than that of the other portions. According to this structure, it is possible to decrease a magnetic reluctance of the magnetic core. Such magnetic core is formed by repeating, to a substrate having a plurality of grooves formed thereon, the step of forming a thin film by using self-shadowing effects of a peak portion of the groove and the step of applying an anisotropic etching process.
