By drawing from the magazine fabricate an engraving by phototypes, and put it in the middle of a uniformly rotating (at a rate of 50 / min) drive. Now, if you got caught in the teeth of a bamboo stick length of 15 cm and a thickness of ¾ inch, at the end of which is set centimeter sewing needle, and easy to press the tip of the needle on the track, starting from the edge of the plate, you can hear as the inventor of the phonograph reads «Handschuh». The sound will be better if my ears with cotton wool. Blockquote> Recording «Handschuh» was photographically reduced to three-quarters of its original size before publication. Her real diameter engraving technique and speed of rotation of 50 rev / min match the recording made November 11, 1889, as described above. All these points suggest that «Handschuh», was probably another disk Berliner, he gave Rosenthal to experiment with the short-lived photomechanical process of copying records. However, this time on the plate was not a demonstration recording Rosenthal, and the record of the poem, which reads Berliner from beginning to end.
After considering all the evidence, my colleague Stephen Puille (Stephan Puille) and I myself have come to the conclusion that the November 11, 1889 Berliner probably showed the recording process Rosenthal, and then sent him home with a label that they did together, as well as several other recorded Berliner earlier.
If we are right, «Der Handschuh» must be the oldest of the two plates, which makes it the oldest known gramophone record, which you can listen to today - the ancestor of all vintage vinyl.
If we made a mistake, it is still, without a doubt, is the oldest known phonograph record, which contains the whole of literature in German - that she did not take away.
In any case, it is right here, at the University Bloomington. Of course, other institutions also store Über Land und Meer, and in some of them, of course, there is a picture «Der Handschuh», but our copy can play and listen , and it does not need to clamp his teeth with bamboo sticks.
