Abstract

PURPOSE: To form two magnetic gaps optimum to recording and reproducing simultaneously into one body with a prescribed dimension, a high precision, simplicity, and high a balance degree by burying previously a metallic narrow wire into one magnetic gap constitution face.
CONSTITUTION: Glass paste 8 is applied onto magnetic gap constitution face 7 of side core 4 having concave groove 6 in a band shape, and metallic narrow wire 9 having a width equal to the recording-side gap width is put on both edges, and side core 11 where glass thin film 10 where wire 9 is buried is formed can be obtained by heating. Paste 8 is also applied onto magnetic gap constitution face 12 of side core 5 partially in a band shape, and side core 14 where glass thin film 13 is formed can be obtained by heating. Next, face 7 of core 4 and face 12 of core 5 are superposed to each other oppositely on gap constitution faces 2 and 3, which constitute completely parallel recording side and reproducing side, of center core 1, and thin films 10 and 13 are melted by heating to cause magnetic gap constitution faces to adhere to each other with glass. After that, the obtained material is cut off along broken lines a to f, thereby obtaining magnetic cores.
