Abstract

PURPOSE: To reduce the cross-feed without increasing the cost, by parallelizing the lamination of the metallic and magnetic foil of high magnetic permeability of I-type core with the gap surface.
CONSTITUTION: The metallic and magnetic substance foil made of permalloy with high magnetic permeability is laminated in parallel with the gap surface 5 to form the I-type core 9 of the recording head and the I-type core 10 of the reproducing head. Thus, the leakage magnetic flux a, b, c, d from the recording coil 7 are shielded magnetically with good efficiency since the magetic substance layer of the I-type cores 9, 10 is orthogonal to the leakage direction to hardly to arrive to the reproducing coil 8 and to decrease the cross-feed. When this magnetic head is used for the device low in the recording and reproducing frequency, the eddy current loss is small and the effect is remarkable.
