Abstract: PURPOSE:To realize high density recording by a high efficiency medium by using a wide gap and high Bs material at the time of write and using a narrow gap and material of which magnetic permeability is high at the time of read. CONSTITUTION:The material of a magnetic substance 2 at a first transition is the same as that of a first and a third magnetic substance at a last transition and it is an MnZn ferrite.

That means, the magnetic pole of the last transition side of a core is a double gap consisting of a butt film 42 which is adjacent to the non-magnetic gap and consists of the first magnetic substance and the magnetic pole of the second magnetic substance 5. The Bs of the MnZn ferrite is 5,000 and the magnetic permeability of 10MHz of it is 1,000. On the other hand, the Bs of the 'Sendust(R)' is 10,000 and the magnetic permeability of 5MHz of it is about 50. Then, the former is used for read and the latter is used for write. Thus, the high recording density can be realized for the high efficiency recording medium.
