Abstract

PURPOSE: To improve frequency characteristics by making it hard for worn powder of a tape to stick by eliminating a breakaway and clearance by strengthening adhesion between the head core of a magnetic head and coating layer with resistance to wear, by providing a glass layer between the core and coating layer.
CONSTITUTION: On the tape opposing surface of head core 1, glass layers 5a and 5b are formed by sputtering to a thickness of 0.01 to several tens μ. Glass layers are only thick enough to serve as adhesives. Next, after this head is installed in head case 3, abrasion-proof coating layer 4 of ceramic is formed of a solvent and circularly polished to complete the head. Improving the eating of flame coating 4 of ceramic by maing the surface of head case 3 uneven improves adhesive strength. Adhesion between core 1 and plasma flame coating 4 also strengthens since flame coating particles intrude into glass layers 5a and 5b while the surface of glass melts at a high temperature of plasma flame coating of ceramic and the speed of flame coating particles.
