ABSTRACT:
A magnetic head with low non-linear transition shift, excellent recording capability at high-frequency bands and good reproduction efficiency is disclosed.
A second metallic magnetic layer of an FeMN system (M : at least one element selected from the group consisting of Ti, Zr, Hf, Nb, Ta and Cr) is formed on the surface facing the gap of the leading-side magnetic core of the magnetic head. On the surface facing the gap of the trailing-side magnetic core of the magnetic head provided is a first metallic magnetic layer of an FeMN system (M : at least one element selected from the group consisting of Ti, Zr, Hf, Nb, Ta and Cr) having a higher saturation magnetic flux density than the second metallic magnetic layer. These two cores are butted against each other via a non-magnetic material and bonded with bonding glass.
