Abstract

a. Circuit pour effacer une bande magnétique portant des données. b. Circuit caractérisé en ce qu'il comporte un montage logique qui, à la réception de signaux déclenchés par l'utilisateur, par l'intermédiaire d'éléments de commande, commute la tête magnétique combinée servant à l'effacement à la lecture et à l'inscription. c. L'invention trouve son application dans le domaine des enregistreurs à cassettes pour télescripteurs.at. Circuit for erasing a magnetic tape carrying data. b. Circuit characterized in that it comprises a logic assembly which, on reception of signals triggered by the user, via control elements, switches the combined magnetic head serving for erasing for reading and for reading. 'registration. vs. The invention finds its application in the field of cassette recorders for teleprinters.
