Development of a Transfer Magnetic Strip Used in Magnetic Card
-
摘要: 介绍了磁卡基本原理和对磁卡用磁条的要求,对3种类型的磁条性能进行了比较。研制出了转移式磁条,其磁性能与进口转移式磁条的磁性能相当,矫顽力2 80~36 0Oe,相对剩余磁通10 0%± 5%。经2 0 0 0次使用后,磁条的读出信号仍大于初始信号的90%。Abstract: The principles of magnetic card and requirements for magnetic strip used in magnetic card are introduced and the performances of three kinds of magnetic strips are compared. A transfer magnetic strip is developed which behaves as those imported products with coercive force 280~360Oe and relative residual flux 100%±5%. The intensity of readout signal keeps above 90% of the initial value after 2000 times use.
