A cut out 23 is formed at the corner portion 22 which is formed between the second long side 822 and each of the first and second short sides 811 and 812 of the back yoke 5, in which the terminal stands 20d of the bobbins 20 of the read/write coil 6 and the erasing coil 7 are disposed respectively, a shield cover 32 is provided in such a manner as it is coupled with the first, second and third leg portions 10a, 10b and 10c including the wiring 6A of the read/write coil 6 and the wiring 7A of the erasing coil 7 and the front core 3 is bonded to the outer body 8 and the shield cover 32. Thereby, the bridging portion which has been necessary in the conventional example is almost eliminated, as a result, the strength of the front core 3 is increased to prevent it from being broken due to any shocking force. Since the terminal stands 20d of the read/write coil 6 and the erasing coil 7 are accommodated in the cut out 23 and not positioned outside the back yoke 5, to that extent, the apparatus is planned to be miniaturized.
