Phonograph cylinder

The earliest method of recording and reproducing sound was on phonograph cylinders. Commonly known simply as "records" in their era of greatest popularity (c. 1888 - 1915), these cylinder shaped objects had an audio recording engraved on the outside surface which could be reproduced when the cylinder was played on a mechanical phonograph. The competing disc-shaped gramophone record system triumphed in the market place to become the domininent commercial audio medium in the 1910s, and commercial mass production of phonograph cylinders ended in 1929.

Preservation of cylinder recordings

Due to the nature of the recording medium, playback of cylinders can cause degradation of the recording. In addition, the equipment for playback is no longer manufactured, which leads to increased difficulty in finding equipment to play the recordings.

In an attempt to preserve the historic content of the recordings, cylinders can be read with a confocal microscope and converted to a digital recording format. The resulting sound clip in most cases sounds better than stylus playback from the original cylinder. Having an electronic version of the original recordings enables archivists to open access to the recordings to a wider audience. This technique also has the potential to allow for reconstruction of damaged or broken cylinders. (Fadeyev & Haber, 2003)
