| Popis: | The description of a method for optomechanical sound reproduction from Edison cylinders the distinctive feature of which is recording the surface profile of the cylinder sound track with its subsequent conversion into sound by means of a computer is presented. With the purpose of decreasing the destructive influence of reproduction system on the cylinder surface the recording the surface profile of a sound track is carried out at rotational speed smaller by a factor of 20 - 30 of that one at which was executed the information recording on it. The realization of a proposed method allowed to reproduce information recorded on cylinders with minimal action and to obtain a high quality of a reproduced signal. |
