金属粉体是一类潜力很大的高密度记录介质,但由于其稳定性差,在大气中极易被氧化腐蚀,因此虽然金属涂布磁带已于1978年投放市场,但氧化问题仍未得到很好解决。80年代前后,在研究金属磁带的抗蚀中,发现氮化铁粉体稳定性高。日本、美国和西欧都进行了研究,但目前公开报道的尚不多。从已有的资料看,日本人的研究较有

Metallic powders are a class of potentially high-density recording media, but due to their poor stability, they are highly susceptible to oxidation in the atmosphere, so although metal coated tapes were introduced in 1978, the problem of oxidation has not been well established Good solution. Before and after the 1980s, in the study of metal tape corrosion, iron nitride powder was found to be highly stable. Japan, the United States and Western Europe have conducted research, but at present there are not many public reports. Judging from the available data, there are more studies in Japan
