Hi there, I bought an used LP and I can see that in a track I have this somehow different trail on grooves. The thing is, this trail is NOT on the whole track,not even from the beginning and not last until the end ( I assume that a feffecrive stylus should mark the whole side of the vinyl and not just a portion). Depend of the angle but you can or not see it and I can’t hear any distorion, pops, static or whatever noise when played… then , what is it?!
I'm going to guess this is marks from a record changer, or from a ring on a rubber mat and slipping (which can happen with some turntables' non-rotating spindle grabbing the record too tight). Looks like you have another concentric mark on the second to last track. Should just be on the top of the land between the grooves, and any debris can be washed off.
