Lines: 12 The problem is that the vinyl problem is essentialy a super cooled liked - there is little order to the material, because it was pressed and chilled. When it is heated, the molecular chains begin to slide across one another and gradually arrange them selves in less energetic positions (ie the material tends to equilibrate). This means that the warping is the obvious manifestation of what is going on at a sub-microscopic scale - the shapes of the groove walls has also deformed. Unfortuantely you'll never be able to restore your disk to its former glory even if you actually mangae to flatten it, because the cutting has been degraded. marcus hand (pyuxt!marcus)
