ABSTRACT:
A floating magnetic head includes a nearly rectangular non-magnetic slider having a floating surface for generating a floating force against a magnetic recording medium, and a magnetic head core including trailing and leading portions made of a magnetic thin film material laminated into a thickness equivalent to a track width and sandwiched by non-magnetic substrates. The magnetic head core is bonded via glass to a side portion of the slider so that a magnetic gap is located on the surface which slides against the magnetic recording medium and the magnetic head core is made shorter than the length of the side of the slider. A chamfered portion is formed in at least one side of the magnetic head core.
