根据消磁器的原理,我利用废收录磁头(消音磁头也行)改作消磁器,给已磁化的录音机磁头消磁,效果良好。其改制方法如下:取一录音机换下的废磁头在两个接线端接入30～36V交流电(磁头内 According to the demagnetizer principle, I use the waste collection head (silencer head also line) demagnetize, magnetized tape recorder head demagnetization, the effect is good. The restructuring method is as follows: take a tape recorder to replace the waste head access to the two terminals 30 ~ 36V AC (magnetic head
