Abstract

Procedure for recording the cancellation or reading of signals on magnetic tapes and by means of a single head, essentially characterized by the fact that the operations of recording, cancellation and reading of the signal on the magnetic tape are carried out by means of a single head simple with two polar expansions, the recording operation being performed by sending to the head itself a signal obtained by adding to the voice frequency signal that the signal of the ultrasonic cancellation frequency must be reproduced.
