PURPOSE:To reduce crosstalk by forming a spacer between a read/write core and an erasing core, of magnetically anisotropical material high in magnetic permeability in the magnetic flux direction of the read/write core. CONSTITUTION:A spacer 3 placed between a read/write core 1 and an erasing core 2 is made of magnetically anisotropical material such as single-crystal ferrite, and has higher magnetic permeability in the direction of the magnetic flux created within the core 1 by a read/write coil 14. Therefore, it is lower in magnetic permeability in the direction crossing the spacer 3 from one coreto the other core and creates the effect to magnetically shield one core against the other core. In such a way, it is possible to reduce the crosstalk. |
