NOT entirely true! Since HOW's & such usually "warp" along one axis (the
paper expands with dampness, while the plastic coating DOESN'T!)...
forcing the centre downward will, at least temporarily, UNwarp the disc...
at least long enough to be played and recorded! It is only the thin plastic
(Goodson, Phonycord, usw.) records that show warpage in complicated
patterns...this most probably explains the short lives of the companies
which sold such phonorecords...?!
