ABSTRACT:
A magnetic head unit comprises erase heads on both sides of a read/write head and an erasing back core having the -shaped cross section consisting of a magnetic material. The back core is engaged with the open end of a rear part opposing to the gap forming region in front of the cores of both erase heads, thereby ensuring high magnetic efficiency, receiving lesser influence of external magnetic field, and improving the magnetic characteristic and back core mounting work efficiency.
