Abstract

The present invention relates to a magnetic head in which a magnetic metal film comprising a Co-containing amorphous alloy and a crystallizable glass of the PbO-B.sub.2 O.sub.3 -ZnO system as a solder glass are used. The magnetic head of the present invention has about 2 times higher recording density than the conventional one as a magnetic head for floppy disks and hard disks because an amorphous alloy is used. Since a crystallizable glass is used as the glass, there can be obtained a magnetic head having a high strength and superior humidity resistance and reliability.
