PURPOSE:To obtain a magnetic head which has high magnetization, low coercive force and high corrosion resistance and permits reproduction of a desired magnetization characteristic by forming at least a part of a magnetically permeable layer of a specific alloy. CONSTITUTION:A magnetic head is constructed by depositing a magnetic film 14 consisting of Co-Ta-Zr on a glass substrate S as a main magnetic pole 17 and protecting the same with a holer 18. The main magnetic pole for vertical magnetic recording is thus obtd. The Co-Ta-Zr alloy has high magnetization, low coercive force and high corrosion resistance and permits reproduction of a desired magnetization characteristic. The magnetic film 14 consisting of Co-Ta-Zr is formed on the opposed surfaces on the magnetic gap 20 side of a core material S consisting of ferrite, by which a magnetic head 27 for audio purpose is obtd. |
