Hi guys. Thanks for the approval. Im new here. I am 32 years of age and only recently got into record collecting (five years now). I have been curious about this "enigma" about uneven/warped vinyl. So this is my question:
Is there a way to grade the degree of "warping" of a vinyl? And if there isn't, how do we say a record is too warped, since most or all vinyl seem to be warped in a certain degree.
Is there a way to reduce the noise created by uneven record? I have read somewhere that you can do that by making adjustment to the armtone. Is that true?
Thanks all!!

Hi Chew - I used to wonder about this too. True - if you inspect vinyl on a turntable, a lot of times it doesn't lay 100% flat. A lot of records have minor body waves that cause the tonearm to rise and fall. To my knowledge there is no grading system for it. I used to have a Pro Ject debut III turntable with an undersized platter, and all my records used to look warped on it and it drove me crazy. I think most collectors consider a warp to be problematic if it affects the sound quality or if the record skips. To reduce warping you can get a record weight that you put on the center of the record over the turntable spindle. There is also a product called vinyl flat - it's a heating system that is supposed to flatten out a warped record. I usually just get rid of unplayable warped records if they're common ones, but I do have a chuck berry 78 that is badly warped that I hope to get flattened out one day.

Bill thanks for the input!! Is there no role by playing around with that tone arm? I have a few records with are warped, and they all caused the tone arm to rise and fall - as you have rightly mentioned - when that happens there are noises created. The higher the arm rises, the stronger it falls and the louder the noise produced. Is there no other way other than flattening the record itself? Thanks!

If you adjust the counterweight on the end of the tonearm, you can make the needle track heavier on the groove, but I don't imagine that would eliminate the weird noise, and it won't get rid of the warp. You can try to get one of those record weights. Or just hold out for a better copy of your record if it's a common one.

I used to put the record between two large books and place it in the sun on a hot day. It worked for me. You might try it.
