Claims
- 1. A magnetic head comprising first and second magnetic core halves held in abutment against each other and a gag-defining spacer interposed therebetween, and having an elongated tape-contact surface extending across said gap-defining spacer, said gap-defining spacer being formed of a material having substantially the same crystal structure as the material forming said first and second core halves said gap-defining spacer being solid-phase welded to said first and second core halves based on a solid-phase reaction.
- 2. A magnetic head as claimed in claim 1, wherein said gap-defining spacer containing at least Al.sub.2 O.sub.3, CaO or a mixture thereof.
- 3. The magnetic head of claim 1, wherein said gap-defining spacer is made of a non-magnetic material having as a major component therein the same major component as that of said first and second core halves.
- 4. The magnetic head of claim 3, wherein said major component is zinc ferrite.
