Warping can most easily be prevented by storing your record
s properly. You should never lay vinyl
records horizontally. This can lead to bowing of the record as gravity acts on the outside, but not on the inside, which is supported by the label
. Store them vertically, on the edge of the sleeve.
Keep your records out of the heat. Heating and cooling cause expansion and contraction, and if the heating or cooling is uneven, your record will have bumps instead of grooves! This means keeping them away from the inside of your parked car if it's sunny. Note: shrink-wrapped records are frequently warped upon purchase. Records from much of Europe typically aren't shrink-wrapped.
