Abstract
In a magnetic head comprising a read/write head and an erase head constructionally integrated with each other, the closed magnetic circuit of the erase head is arranged to be higher in magnetic reluctance than the closed magnetic circuit of the read/write head, whereby a magnetic flux to be drawn by the erase gap is reduced so as to prevent the leakage of the magnetic flux to the read/write head side.
