    Abstract: PURPOSE:To suppress the stresses generated at the time of joining by changing the thickness of a reaction layer generated between glass and ceramics to change an apparent fixing point. CONSTITUTION:The control of a reaction layer quantity is executed by changing viscosity, i.e., temp. and holding time in a glass pack stage. The reaction layer increases as the viscosity is lower and the temp. is higher and the pack time, i.e., the heating and holding time, is longer. Tension stresses increase as the thickness of the reaction layer is larger. As a result, the amt. of the reaction layer is optimized without changing the material of the glass and ceramics and the generated stresses are suppressed by substantially controlling the apparent fixing point thereof.

    Abstract: PURPOSE:To enhance the reproduction efficiency over the entire part of a head core by aligning the easy magnetization directions of magnetic metallic layers in effective track width constituting parts among the magnetic metallic layers to be laminated via insulating layers and non-paralleling the easy magnetization directions of the other parts. CONSTITUTION:The magnetic metallic layers 1, 2 are multilayered films formed by laminating the plural magnetic metallic layers 1a...1g, 1h, 2a...2g, 2h via the insulating films 11, 12. The individual easy magnetization directions of the adjacent magnetic metallic layers 1a...2h are the same as the easy magnetization directions of the effective track width constituting parts and are non- paralleled in the other parts. As a result, the recording and reproducing efficiency in a magnetic gap part is improved and the reproduction efficiency over the entire part of the head core is enhanced. Then, the remarkable improvement in the head output is expected.

    Abstract: PROBLEM TO BE SOLVED: To enhance yield and production efficiency by using a low melting point glass having a specified viscosity at the heat treatment temperature of a metallic magnetic thin film diagonally formed on a substrate as a nonmagnetic material for flattening the substrate. SOLUTION: The viscosity of the low melting point glass 30 at the heat treatment temperature of the metallic magnetic thin film is 102-106Pa.s. The glass 30 is melted and perfectly filled all over one principal face of the substrate 21 with magnetic core forming grooves, separation grooves 28 and winding grooves 29 as well as the metallic magnetic thin film. Since the glass 30 is filled at such a temperature that the metallic magnetic thin film ensures good soft magnetic characteristics, the heat treatment of the thin film is made unnecessary. The glass 30 is then solidified by cooling and the surface is ground to flatten the substrate. A terminal for connection to the outside and a thin film coil are formed, nonmagnetic films are diffused to each other and a pair of magnetic core half blocks are integrated by joining to manufacture a magnetic head block.

    Abstract: PROBLEM TO BE SOLVED: To improve the electromagnetic conversion characteristic of a magnetic head. SOLUTION: A magnetic core 9 in which a magnetic path is formed to record and to reproduce recording signals against a magnetic recording medium, is tilted to the approximately same direction of an azimuth angle of a front gap 14 using the direction that is orthogonal to the sliding direction of the medium as a reference on the sliding surface of the medium. Thus, the width of a narrow section that is made narrower by an abutting width control groove 11, is formed longer in the core 9.
