A magnetic head comprises a pair of magnetic core halves, heat-resistant thin films and ferromagnetic thin films, the pair of magnetic core halves being opposed to each other through a non-magnetic material such as SiO2 to form a magnetic gap. The magnetic core halves are made of a ferromagnetic oxide such as ferrite and have gap forming faces to be opposed to each other to form the magnetic gap. The gap forming faces are etched by phosphoric acid solution and then purified by reverse sputtering, so that a grown crystal of the ferromagnetic oxide is expo...
A method of manufacturing a magnetic core half in a magnetic head having a magnetic gap between a pair of said magnetic core halves opposed to each other through a non-magnetic material, a vicinity of said magnetic gap including ferromagnetic metal material, said method comprising the steps of: preparing a magnetic core half member made of a ferromagnetic oxide and having a gap forming face to be opposed to form said magnetic gap; treating said gap forming face to cause said gap forming face to have an appearance exposing a grown crystal of said ferromag...
