在磁记录材料中,磁带的增长速度十多年来平均每年超过15%.1983年全世界磁带的总产量估计已超过4000亿米(以带宽6.25毫米磁带为准),盒式录音磁带的产量超过17亿盒(以C60磁带为准),广泛应用于广播、通信、电影、电视、文化艺术、教育、医疗卫生、地质勘探、宇宙空间技术以及军事、情报等领域,并深入家庭,与人们的关系越来越密切.在工业产品中,录音磁带的发展历史并不长.虽
In magnetic recording materials, tapes have grown at an average rate of more than 15% per year for more than a decade. In 1983, total tape production worldwide was estimated at more than 400 billion meters (based on a 6.25-mm tape), tape cassette production Over 1.7 billion boxes (based on C60 tapes) are widely used in the fields of broadcasting, telecommunications, film, television, arts and culture, education, health care, geological exploration, space technology and military and intelligence, The relationship between the more and more closely.In the industrial products, the development history of tape recording is not long.
