I got here a few records which looked if they are scratched. The scratches (if they are scratches) look like grooves. (They lay exact in the same direction as the grooves) But if I listen to this records, you hear nothing, just music. No cracks or jumps or something in between, only music.
I tried to make two pictures, where you can slightly see the scratches.
Can someone tell me what this is. Are these light scratches or do they only look like scratches.
