More than 12 different formats
Within this nomenclature, different groove formats, chemical composition, rotation speed, diameter, etc. are included. They are the oldest audio formats and also the most delicate ones. Starting with the Edison cylinders of brown wax (actually soda stearate and vegetable waxes) whose improper handling can result in large caliber breaks, or for example a sudden thermal difference, can cause cracks that eventually result in significant breaks. To be able to digitize this type of files we have the Arheophone, a universal reader with adjustments for correction of deformations, speed and various diameters.
