磁気ヘツドの構造。[Claims for Utility Model Registration] (1) A magnetic gap for recording and reproduction is formed by abutting two magnetic cores made of ferrite, and a non-magnetic underlayer film and the underlayer film are provided on the abutting surfaces of the magnetic cores. In a magnetic head having a high saturation magnetic flux density material film formed thereon, the underlayer film and the high saturation magnetic flux density material film are formed on at least one of the magnetic cores, and the underlayer film is formed on at least one side of the magnetic recording medium. A structure of a magnetic head for high-density recording/reproduction, characterized in that the magnetic head is formed in the vicinity of contact. (2) In the structure described in claim (1) for utility model registration, the underlayer film is formed on the abutting surface of the magnetic core, and the thickness of the underlayer film is such that the underlayer film comes into contact with the magnetic recording medium. 1. A structure of a magnetic head for high-density recording/reproduction, characterized in that the thickness of the magnetic head other than the part is smaller than the thickness of the magnetic head.
