Description
Hör- oder Sprechkopf für Mehrspuraufzeichnung bei der magnetischen Schallaufzeichnung In der Schallaufzeichnungstechnik entsteht häufig die Aufgabe, mehrere getrennte Tonspuren auf ein und demselben Aufzeichnungsträger aufzubringen. Für die Durchführung dieser Aufgabe fehlte es bisher an einem geeigneten Sprechkopf, wenn die Schallaufzeichnung auf magnetischem Wege vorgenommen werden soll.Listening or speaking head for multi-track recording with magnetic Sound recording In sound recording technology, the task often arises to apply several separate audio tracks on one and the same recording medium. So far there was no suitable headset to carry out this task, if the sound recording is to be made magnetically.
Es ist bereits ein Hör- oder Sprechkopf zur Längsmagnetisierung von bandförmigen Tonaufzeichnungsträgern nach dem Gegentaktverfahren unter Verwendung zweier getrennter Tonspuren bekannt, bei dem je zwei .zu verschiedenen Einzelköpfen gehörende Kernteile unter Einfügung einer Abschirmplatte aus unmagnetischem Material fest miteinander verbunden sind, so daß sie beim spiegelbildlichen Zusammenfügen mit den beiden anderen Kernteilen einen genau fluchtenden gemeinsamen Arbeitsluftspa,lt bilden.It is already a listening or speaking head for longitudinal magnetization of tape-shaped sound recording media by the push-pull method using two separate audio tracks known, each with two .zu different individual heads Corresponding core parts with the insertion of a shielding plate made of non-magnetic material are firmly connected so that they are mirror-inverted assembly with the other two core parts a precisely aligned common working air space, according to form.
In Weiterentwicklung dieser Anordnung besteht nun die Erfindung darin, daß drei oder mehrere Einzelmagnetköpfe zu einem System zur Aufzeichnung von drei oder mehreren Spuren vereinigt sind.In a further development of this arrangement, the invention now consists in that three or more individual magnetic heads to a system for recording three or several tracks are combined.
Ein solcher Magnetkopf bietet eine Reihe wichtiger Vorteile. Er kann durch Hinzufügen beliebiger Kernteile zu einem System für beliebig viele Spuren ausgebaut werden.Such a magnetic head offers a number of important advantages. He can by adding any core parts to a system for any number of tracks get extended.
Zur Erzielung besonders guter Ergebnisse werden gemäß weiterer Ausbildung der Erfindung die Abschirmplatten zwischen den Einzelköpfen verschieden stark und aus verschiedenem Material gewählt. Beim Sprechkopf können: sie dünner sein als beim Hörkopf.In order to achieve particularly good results, further training is required of the invention, the shielding plates are different between the individual heads strong and chosen from different material. With the speaking head: they can be thinner than with the ear head.
Beim Hochfrequenz-Vormagnetisierungsverfahren wird man die Abschirmplatten zweckmäßigerweise aus Kupfer herstellen, weil dadurch ein Übersprechen der Hochfrequenz zwischen den einzelnen Kopfteilen vermieden wird.In the high-frequency bias process, one becomes the shielding plates Expediently made of copper, because this causes crosstalk of the high frequency between the individual headboards is avoided.
Um auch ein Übersprechen der Tonfrequenzen zu vermeiden, kann man die Abschirmplatten aus einem hochpermeablen Material herstellen und auf beiden Seiten durch unmagnetische Materialien gegen die Einzelköpfe magnetisch isolieren oder mit einem Kupferüberzug versehen.In order to avoid crosstalk of the audio frequencies, one can Make the shielding plates from a highly permeable material and on both Magnetically isolate the sides from the individual heads using non-magnetic materials or provided with a copper coating.
Schließlich kann auch noch in ein und demselben Magnetsystem ein zusätzlicher Einzelkopf zur Aufzeichnung und Wiedergabe von Steuersignalen vorgesehen werden.Finally, an additional magnet system can also be used in one and the same magnet system Single head can be provided for recording and reproducing control signals.
