矫顽力和剩磁为普通γFe_2O_3磁带三倍以上的高性能合金磁带将于78年底～79年初投入市场。目前这种磁带主要用于盒式录音机,今后将在电子计算机等其他使用磁记录的领域中应用。合金磁带即合金磁粉磁带,不同于用蒸发、溅射、化学沉积或电沉积制成的金属薄膜磁带,它是把以 Fe 为主并含有 Co、Ni 成分的合金微粉和粘结剂混合成磁浆,然后采用和制造γFe_2O_3磁带相同的方法将磁浆涂布到带基上。这种合金微粉是强磁性体。它与γFe_2O_3和 CrO_2
High-performance alloy tape with coercivity and remanence more than three times that of ordinary γFe_2O_3 tape will be put on the market by the end of 78 ~ early 79. Currently, such tapes are mainly used in cassette recorders and will be used in other fields such as electronic computers and the like where magnetic recording is used. Alloy magnetic tape or alloy magnetic tape, different from the use of evaporation, sputtering, chemical deposition or electrodeposition of metal film tape, which is the main Fe and containing Co, Ni composition of the alloy powder and binder mixed into a magnetic The slurry was then applied to the tape base using the same method used to make the gamma Fe_2O_3 tape. This alloy powder is a ferromagnetic body. It is with γFe_2O_3 and CrO_2
