Preservation of Data in Gramophone Record by Non-contact and Non-destructive Fully Scanning Method

The digital archiving is the major method in recording the analog records, but in usually it has a problem in itself that it destroys the object while running the stylus. Using the fact that the sound information in wax cylinders and analog records is recorded throughout the sound groove, we have tried modifying the Signal-to-Noise ratio [1]. Having these as our background, we are aiming for the establishment of a new method in which one could read as much information as possible off of wax cylinders and early SP analog records without making contact and destroying it. In this report, by fully scanning wax cylinder with laser beams we've tried to image the virtual record on computer from which we can make a replica if needed. And pick out as much information as possible from the recordings. 1
