摘要： A floating type composite magnetic head includes a head core fixed to a slider formed of nonmagnetic material. In the head core, a pair of magnetic core halves are abutted against each other with nonmagnetic material such as SiO.sub.2 or the like interposed therebetween. The first and second magnetic core half members have first and second gap forming surfaces to be abutted against each other to define a magnetic gap (g), respectively. A first groove is formed on the second gap forming surface. A glass layer is formed in the first groove. A first thin film including a ferromagnetic metal thin film is selectively formed on the first gap forming surface. A second thin film including a ferromagnetic metal thin film is selectively formed on the second gap forming surface so that at least a portion except the surface of the glass layer in the second gap forming surface is exposed. A second groove is formed on the exposed second gap forming surface adjacent to the first groove. The first and second magnetic core half members are abutted and bonded with glass so that the first and second gap forming surfaces face each other so that the first and second thin films are abutted with SiO.sub.2 or the like interposed therebetween to define a magnetic gap (g). Causes of occurrence and an increase of false gaps are suppressed and a decrease in manufacturing yield due to separation of thin films or the like can be prevented.
