Description

Verfahren und Vorrichtung zur Herstellung einer Mehrzahl gleicher Magnetogramme Magnetofonbänder werden bisher im Umspielverfahren vervielfältigt. Um mehrere Bänder mit gleichen Darbietungen herzustellen, ist es notwendig, ein Band nach dem anderen und je für sich mit den Darbietungen eines erstbespielten Originalbandes bzw. eines anderen Aufzeichnungsträgers oder mit der ständig zu wiederholenden Originaldarbietung selbst zu bespielen.Method and apparatus for producing a plurality of the same Magnetograms Magnetophone tapes have so far been duplicated using the play-around process. In order to produce several tapes with the same performances, it is necessary to use a Volume after the other and each for itself with the performances of a first recorded Original tape or another recording medium or with the one that has to be repeated over and over again Record the original performance yourself.

Dieser umständliche Vorgang wird durch die Erfindung wesentlich vereinfacht. Sie verfährt so, daß ein Aufnahmeband, im wesentlichen von der vielfachen Breite eines normalgebräuchlichen Wiedergabebandes, zunächst mit der aufzunehmenden Darbietung bespielt, sodann seiner Länge nach in beliebig viele Wiedergabebänder geschnitten wird. Ein Sprechkopf ausreichender Breitenwirkung Sorgt dabei für eine gleichmäßige Magnetisierung des Aufnahmebandes über seine gesamte Breite hinweg, so daß gleiche Wiedergabeeigenschaften der geschnittenen Bandstreifen untereinander gewährleistet sind. Durch geeignete Bemessung der Aufnahmemagnetisierung hat man es ferner in der Hand, die Wiedergabestärke aller Bandstreifen der des benutzten Originalbandes anzugleichen.This cumbersome process is significantly simplified by the invention. It proceeds so that a recording tape, essentially of the multiple width of a normal playback tape, initially with the performance to be recorded recorded, then cut lengthways into any number of playback tapes will. A speaking head of sufficient width ensures a uniform effect Magnetization of the recording tape over its entire width, so that the same Reproduction properties of the cut tape strips among each other guaranteed are. By appropriately dimensioning the recording magnetization, it can also be found in by hand, the reproduction strength of all tape strips is that of the original tape used to adjust.

Die Erfindung läßt auch sehr schmale Magnettonbänder gewinnen, bei deren geringer Breite ein gesondertes Bespielen nur schwer möglich wäre; z. B. können danach aus einem bespielten Magnettonband mit 6,5 mm Normalbreite schmale Tonstreifen von i mm Breite oder darunter geschnitten werden, die sodann in geeigneter Verbindung mit Bildfilmen, insbesondere Schmalfilmen, zu deren Vertonung verwendbar sind.The invention can also win very narrow magnetic tapes the narrow width of which a separate example would be difficult to achieve; z. B. can then from a recorded magnetic tape with 6.5 mm normal width narrow sound strips cut i mm wide or less which are then in suitable connection with picture films, especially cine films, for setting them to music are usable.
