Vinyl recorder
A vinyl recorder is a technical device for cutting your own records in single and small editions in contrast to the industrial production of records by pressing.
The vinyl recorder is u. a. as an attachment for turntables with powerful motors. The groove is cut with a diamond or sapphire graver on raw PVC sheets or metal sheets coated with lacquer or acetate . In most cases, the cutting stylus is moved from the outside to the inside over the disk, which is rotating at playback speed. The sapphire or diamond forms the groove by moving the coils to which the amplified mono or stereo signal is applied vertically and horizontally to the surface of the plate. It is also possible to make the groove not spiral, but circular. During playback, the cut information is then repeated in the form of an endless loop with each rotation .
The quality of the recorded records is comparable with average, commercially available pressings, but does not come close to the professional cutting systems in terms of volume and distortion factor . B. is about making extreme heights or particularly lifelike records.
One advantage is the better signal- to- noise ratio compared to pressed records, since no galvanic molding or material properties of the molding compound play a role here.
