ABSTRACT:
A magnetic head in which a first magnetic film made of a material of high saturation magnetic flux density is deposited on the surface of a block made of a high permeability material and which contains a groove for winding. A nonmagnetic film made of a nonmagnetic material and serving as a magnetic gap is formed on the first magnetic film; and a second magnetic film made of a material of high saturation magnetic flux density is further formed on the nonmagnetic film. A reinforcing block is arranged on the second magnetic film and has a nonmagnetic material portion exposed to a slide surface of a recording medium. The high permeability material block, the first magnetic film and the second magnetic film together constitute a magnetic core, and the second magnetic film is bonded with the reinforcing block.
