本文对目前盒式收录机用音频磁头生产中所使用的软磁合金作了详细的分析和讨论,对用国产与进口材料制造的磁头主要性能指标作了比较,并提出了国产材料目前存在的问题及尚需改进的方面,尤其对八十年代适于金属磁带用的磁头材料,从磁头的设计方案论证了有关磁性能的必要限度值,并将试制磁头与国外同类产品的性能作了比较,以供从事金属带磁头的设计师及新材料开发的广大工程技术人员参考。
This paper analyzes and discusses in detail the soft magnetic alloy used in the audio head production of cassette recorders at present, compares the main performance indexes of the heads manufactured by domestic and imported materials, and presents the existing problems of domestic materials In addition, the necessary improvement of the magnetic properties, especially for the magnetic head material suitable for metal tape in the 1980s, has been verified from the design of the magnetic head. The comparison between the performance of the trial magnetic head and the similar foreign products has been made. For metal heads with designers and new materials development of the vast number of engineering and technical personnel for reference.
