用磁気ヘツド。[Claims for Utility Model Registration] A component 1 in which a first spacer made of a plate-shaped non-magnetic material and having the same thickness as the magnetic core is bonded to a plate-shaped magnetic core for recording and reproduction having a magnetic gap for recording and reproduction. The above-mentioned recording and reproducing method is performed using two constituent members, each of which is a plate-shaped erasing magnetic core having an erasing magnetic gap and a second spacer made of a plate-shaped non-magnetic material having the same thickness as the magnetic core. The recording/reproducing magnetic core and the erasing magnetic core are brought into contact with each other by arranging the second spacers on both sides of the recording magnetic core and the erasing magnetic cores on both sides of the first spacer. In the magnetic head for a floppy disk, which is arranged so that the erasing coil is not erased, an erasing coil back bar and a connecting back bar for mounting the erasing coil are suspended between the pair of erasing magnetic cores. A closed-loop erasing magnetic path is formed through each member: coil back bar → magnetic gap of one erasing magnetic core → connecting back bar → magnetic gap of the other erasing magnetic core → erasing coil back bar. A magnetic head for a floppy disk.
