ABSTRACT:
A method for manufacturing a video magnetic head in which two soft magnetic core halves (2a, 2b) of amorphous metal are connected via a non-magnetic gap (5) and the core halves are bilaterally supported by core supports (3a, 3b; 4a, 4b) of ferrite. The core halves with the core supports are combined to a core compound by melting a thin low melting point glass layer (7) which is sputtered on the core halves. The combination process is effected by means of simultaneous influence of temperature and pressure.
