摘要： A magnetic recording medium suitable for use in a recording system employing a magnetic recording transducer or head of the single-pole type which operates in a perpendicular magnetization mode comprises a non-magnetic base supporting a layer of low coercive force material formed on the base and which underlies a magnetic recording layer. The magnetic recording layer which faces the magnetic recording transducer or head is formed of an alloy composed mainly of chromium and cobalt and has an easy axis of magnetization perpendicular to the surface of the magnetic recording layer, with the thickness of the latter being no greater than 3.0 microns. The low coercive force material layer has a coercive force no greater than 1/5 of the coercive force of the magnetic recording layer, and the thickness of the low coercive force layer is greater than 0.1 microns.

摘要： In the method of producing reduced iron according to the invention, fine iron oxides and powdery solid reductants are mixed, compacted into sheet-like compacts, and charged onto the hearth of a reduction furnace for reduction while maintaining the temperature inside the furnace at not less than 1100° C. As the sheet-like compacts can be obtained by compacting mixture of raw material by use of rollers or the like, processing time is much shorter than the case of pelletization or agglomeration. A drying step is unnecessary since feeds are placed no the hearth via a feeder chute or the like. The method is carried out with ease by use of the facility according to the invention. High quality hot metal can be produced by charging reduced iron in hot condition obtained by the method described as above into a shaft furnace or a in-bath smelting furnace for melting at high thermal efficiency.
摘要翻译：在根据本发明的还原铁的制造方法中，将细小的氧化铁和粉末状固体还原剂混合，压实成片状压块，并将其装入还原炉的炉床中进行还原，同时保持炉内的温度不低于由于可以通过使用辊等压缩原料的混合物而获得片状压块，所以加工时间比造粒或凝聚的情况短得多。干燥步骤是不需要的，因为进料通过进料槽或类似物不放置在炉床上。该方法通过使用根据本发明的设备容易地进行。可以通过将通过上述方法获得的热状态的还原铁装入竖炉或熔池熔炼炉中，以高的热效率进行熔化，可以生产高品质的铁水。

摘要： A thin-film single magnetic pole head which assures highly efficient magnetic energization of a main magnetic pole and which exhibits optimum recording characteristics even in case of recording on a double-layer perpendicular magnetic recording medium with a high frequency. The thin-film single magnetic pole head includes a main magnetic pole consisting of a soft magnetic thin film and a return yoke. A thin-film coil for energizing the main magnetic pole is constituted by a plurality of conductor layers extending substantially parallel to one another and substantially at right angles to the main magnetic pole. The conductor layers are layered together in the up-and-down direction on both sides of the main magnetic pole. A thin-film coil for magnetically energizing the main magnetic pole is constituted by selectively interconnecting the conductors. In this manner, the thin-film coil can be arranged at the foremost part of the main magnetic pole (towards the perpendicular magnetic recording medium facing surface) to render it possible to energize the foremost part of the main magnetic pole with high efficiency.
