Description
Gegenstand der Hauptanmeldung P 1473 804.6-52 ist ein wegstreckenabhängiger, bandförmiger Programmspeicher zum Speichern oder Feststellen von Programmbefehlen in Abhängigkeit von einer Wegstrecke für zwei relativ zueinander bewegbare Körper unter Bewegung des Programmspeichers durch eine Rolle proportional zur Drehung einer Andrucksrolle, die an einem der beiden Körper angebracht ist und sich auf dem anderen Körper abwälzt, wobei der als Magnetband ausgebildete Programmspeicher mehrspurig ist und ein Abtastkopf zugleich mehreren Spuren zugeordnet ist.The subject of the main application P 1473 804.6-52 is a distance-dependent, band-shaped program memory for storing or determining program commands depending on a distance for two bodies that can move relative to one another while moving the program memory a roller proportional to the rotation of a pressure roller attached to one of the two bodies and rolls on the other body, the program memory designed as a magnetic tape is multi-track and a scanning head is assigned to several tracks at the same time.
Gemäß der Hauptanmeldung schwingt der Magnetkopf mit einer bestimmten Mindestgeschwindigkeit zwischen einer Doppelspur des Programmspeichers hin und her. Diese Einrichtung hat den Nachteil, daß die Bandbreite um das Doppelte zunimmt und daß der Weg, in dem der Kopf schwingen muß, etwa einen Millimeter beträgt.According to the parent application, the magnetic head oscillates at a certain minimum speed back and forth between a double track of the program memory. This device has the disadvantage that the bandwidth doubles and that the way in which the head has to swing is about one millimeter.
Die Erfindung vermeidet diesen Nachteil und sieht vor, daß zur Abtastung der Spuren der Abtastkopf und das Magnetband in an sich bekannter Weise periodisch senkrecht zueinander schwingen.The invention avoids this disadvantage and provides that the scanning head is used to scan the tracks and periodically oscillate the magnetic tape perpendicular to one another in a manner known per se.
Die Induktionswirkung wird also dadurch erzielt, daß der Kopf senkrecht zum Magnetband schwingt, da schon eine geringe Luftspaltänderung eine hohe induktive Impulswirkung zur Folge hat.The induction effect is achieved by the head vibrating perpendicular to the magnetic tape, because even a small change in the air gap results in a high inductive pulse effect.
Gemäß einem vorteilhaften Merkmal der Erfindung sollen der oder die Abtastköpfe gemeinsam an einem zum Magnetband senkrecht angebrachten Schwinger befestigt sein, der in an sich bekannter Weise,.z. B.,.durch eine Tauchspule, zum Schwingen angeregt wird. Auch kann an Stelle des Schwingers eine exzentrisch gelagerte Anpreßrolle verwendet werden. Schließlich kann auch ein flußempfindlicher Magnetkopf verwendet werden.According to an advantageous feature of the invention, the scanning head (s) are intended to work together a transducer attached perpendicular to the magnetic tape, which is known per se Way, .z. B.,. By a moving coil, for oscillation is stimulated. An eccentrically mounted pressure roller can also be used instead of the oscillator will. Finally, a flow sensitive magnetic head can also be used.
Die Fig. 1 zeigt schematisch in einem Ausführungsbeispiel ein Magnetband 10 vor einem Kopf 11, der von einem schwingfähigen System, bestehend aus Spule 12 mit Eisenmantel 13 und Schwinganker 14 in Richtung senkrecht zum Magnetband in Schwingungen versetzt wird: Bei dem Ausführungsbeispiel :Fig. 1 shows schematically in one embodiment a magnetic tape 10 in front of a head 11, which is composed of an oscillatory system Coil 12 with iron jacket 13 and oscillating armature 14 vibrates in the direction perpendicular to the magnetic tape is offset: In the embodiment:
F i g. 2 wird der Luftspalt zwischen dem Magnetband und dem Kopf 11 durch die umlaufende exzentrisch gelagerte Anpreßrolle 15 periodisch verändert. Die F i g. 3 zeigt einen flußempfindlichen Kopf 16 vor dem Magnetband 10, der unabhängig von der Bandgeschwindigkeit bei konstantem Luftspalt ein Signal vom Magnetband aufnehmen oder auf das Magnetband geben kann.F i g. 2, the air gap between the magnetic tape and the head 11 is eccentric due to the circumferential mounted pressure roller 15 changed periodically. The F i g. 3 shows a flow sensitive head 16 the magnetic tape 10, which is independent of the tape speed with a constant air gap a signal can pick up from the magnetic tape or put on the magnetic tape.
