    • An iron-aluminum-silicon (Fe-Ai-Si) series magnetic alloy magnetic head and a manufacturing method therefor. The magnetic head includes front gap forming surfaces which serve as the magnetic tape transportation surfaces and comprise a non-magnetic ceramic films and glass films, and rear gap forming surfaces aiming at junction at the portion reverse to the tape transportation side and comprising either the same materials at the front gap or silver-copper series alloy films. The manufacturing method forms by means of sputtering non-magnetic ceramic films at the front gap forming surfaces of the core pieces and either non-magnetic ceramic films or silver-copper series alloy films at the rear gap forming surfaces, in some cases implanting ion onto the films, and allowing the cores to abut against each other, so that the cores are subjected to heat treatment in a non-oxidizing atmospher less than or more than atmospheric pressure and at a temperature higher than the softening point of the glass and the liquid phase appearance temperature of the silver-copper series alloy.
    • 铁 - 铝 - 硅(Fe-Al-Si)系列磁性合金磁头及其制造方法。 磁头包括用作磁带传送表面的前间隙形成表面,并且包括非磁性陶瓷膜和玻璃膜,以及在与带传送侧相反的部分处的接合处的后间隙形成表面,并且包括相同的 前隙材料或银铜系列合金膜。 该制造方法通过在芯片的前间隙形成表面处溅射非磁性陶瓷膜和在后间隙形成表面处的非磁性陶瓷膜或银 - 铜系合金膜形成,在某些情况下将离子注入到 并且允许芯彼此抵接,使得芯在低于或大于大气压的非氧化性气氛中并且在高于玻璃和液体的软化点的温度下进行热处理 银 - 铜系列合金的相出现温度。
