Claims
- 1. An iron-aluminum-silicon (Fe-Al-Si) series magnetic alloy head for a magnetic recording medium, consists essentially of:
- a pair of Fe-Al-Si alloy core pieces which respectively have front gap forming surfaces forming therebetween a front gap facing said magnetic recording medium and rear gap forming surfaces forming therebetween a rear gap for junctioning said core pieces;
- ceramic films formed respectively on said front gap forming surfaces of said core pieces;
- a glass film filling a gap between said ceramic films; and
- a silver-copper-indium (Ag-Cu-In) series alloy film filling said rear gap.
- 2. An iron-aluminum-silicon (Fe-Al-Si) series magnetic alloy head according to claim 1, wherein each of said ceramic films consists essentially of a film selected from the group consisting of zirconium oxide (ZrO.sub.2), magnesium oxide (MgO), spinel (MgO.Al.sub.2 O.sub.3) and silicon oxide (SiO.sub.2).
- 3. An iron-aluminum-silicon (Fe-Al-Si) series magnetic alloy head according to claim 1, where in said glass film consists essentially of a lead oxide-sodium oxide-silicon oxide (PbO-Na.sub.2 O-SiO.sub.2) series alloy glass film.
- 4. An iron-aluminum-silicon (Fe-Al-Si) series magnetic alloy head according to claim 3, wherein said lead oxide-sodium oxide-silicon oxide (PbO-Na.sub.2 O-SiO.sub.2) series alloy glass film contains 20 to 80 wt% of SiO.sub.2.
- 5. An iron-aluminum-silicon (Fe-Al-Si) series magnetic alloy head according to claim 1, wherein said silver-copper-indium (Ag-Cu-In) series alloy film consists essentially of 20 to 85 wt% of silver (Ag), 10 to 50 wt% of copper (Cu) and 1 to 30 wt% of indium (In).
