Description

Verfahren zur Prüfung der Spaltneigung an Magnettongeräten Hei den Geräten zur Aufnahme und Wiedergabe von Schalleindrücken auf magnetischem Wege ist es erforderlich, daß die Spalte des Sprech- und Hörkopfes sowohl auf ein und derselben Totibandniaschine wie auch im 1'crli<iltriis zu anderen l,xeniplaren solcher Geräte finit größter Präzision parallel stehen. Die Einstellung der Spalte erfolgt heute nach verschiedenen Verfahren, optisch oder elektrisch. Diese \herfahren sind meist umständlich und zeitraubend und bringen häufig nicht den gewünschten Grad der Genauigkeit.Method for testing the tendency to gaps on magnetic recorders Devices for recording and reproducing sound impressions by magnetic means is it required that the column of the speaking and listening head be both on one and the same Dead band tie machine as well as in the 1'crli <iltriis to other l, xeniplaren such Devices are finite in parallel with the greatest precision. The column is set today by different processes, optical or electrical. These \ have come here mostly cumbersome and time-consuming and often do not achieve the desired degree of accuracy.

Erfitidtingsgeniiil.# wird die Einstellung und Priifung der Spalte finit großer Genauigkeit möglich durch Verwendung von Prüfbändern, bei denen ein "hon in zwei nebeneinander herlaufenden Spuren so aufgezeichnet ist, dal.i die eine Spur mit der positiven und die andere Spur mit der negativen Ilalbwelle aufgezeichnet sind, wodurch bei der genieinsanien und gleichzeitigen _\litastntig beider Spuren durch einen richtig einjustierten Kopf die von heilen Spuren gegenphasig induzierten Spannungen gleich sind und sich in ihrer Wirkung dadurch aufheben. Bei genauer Spalteinstellung ist beim Vorbeilaufen des Prüfbandes deshalb kein Ton zu hören, während jede Spaltneigung nach der einen oder anderen Seite hörbar wird. In gleicher Weise k<intieti natürlich auch Aufnahmen mit mehr als einem Paar vom Tonspuren verwendet werden.Erfitidtingsgeniiil. # Is setting and checking the column finitely high accuracy possible by using test tapes in which a "hon is recorded in two tracks running side by side in such a way that one Track recorded with the positive and the other track with the negative half-wave are, whereby in the genieinsanien and simultaneous _ \ litastntig both tracks by a correctly adjusted head those induced by heal traces out of phase Tensions are equal and their effect is canceled out. With precise gap adjustment therefore no sound can be heard when the test tape passes, while there is a tendency to split becomes audible to one side or the other. In the same way k <intieti of course Recordings with more than one pair of sound tracks can also be used.
