ABSTRACT:
A cartridge for endless magnetic tape loops including a cover containing a pair of supports substantially coplanar with the other and between which is wound a magnetic tape in lengthening coils. A third support guides a connecting coil which connects the innermost coil with the outermost coil of the loop. The third support is substantially coplanar with the pair of supports in such a way that the connecting coil is substantially coplanar with the other coils of the tape recording and/or reading device for a magnetic tape contained in a cartridge which includes at least one window through which the tape contained therein may be reached. The device includes a capstan, a pressure roller and a magnetic recording and/or reading head mounted on an activation lever. A spring element normally holds this lever against the action of a pressure spring. The insertion of the said cartridge removes the spring element so as to free the said activation lever and leave it in a working position in which the pressure roller and magnetic head are brought into contact with the tape.
