PURPOSE:To form a magnetic head having high peeling strength and high reliability, by providing specific thin film surface layers on a thin plate consisting of ferromagnetic materials and using an inorganic adhesive to join this thin plate and a guard member. CONSTITUTION:In a process (i), first, thin film surface layers (thickness of 100Angstrom -5mu) 2 and 2 consisting of an activated metal such as Ti and Cr and second thin film surface layers (thickness of >=200Angstrom ) 3 and 3 consisting of a metallic oxide such as SiO2 and Al2O3 are formed on surfaces of a thin plate 1 consisting of an amorphous ferromagnetic alloy such as Co-Fe-B-Si; and in a process (ii), these thin plates 1 consisting of the amorphous ferromagnetic alloy and nonmagnetic guard members 4b consisting of ceramic or the like are laminated guard members 4b consisting of ceramic or the like are laminated alternately and are adhered to each other by an inorganic adhesive such as a low- melting point glass, thus forming a layered block 5. In a process (iii), the layered block 5 is sliced in the direction orthogonal to the junction face to obtain core block pieces 6, and a core block obtained by joining a pair of core block pieces is worked in the known method and is sliced in parts of guard members 4b, thus obtaining individual head cores 11. |
