Abstract

A method of reproducing signals from a magnetic tape having two signals recorded therein, said method including the operations of arranging similar first and second inductors in inductive relationship with said two signals recorded respectively and in inductive relation similar to any external electromagnetic field, inducing in said inductors first and second electric signals representative of said two recorded signals, respectively, and combining the outputs of said inductors so that any signals induced in said inductors by said external electromagnetic field are summed in opposition.
