Re: [ARSCLIST] Dynagroove, was Record tracking



Sorry, I don't have any specifics. The secret was revealed by a Columbia executive at a public radio music programmers' conference in about 1974.

During that period, US Columbia discovered that they could substitute cellophane (or some other clear film) for vinyl. They were buying huge rolls of the stuff, without ever explaining to the supplier what it was being used for. I don' think it was the same stuff they used for shrink-wrap, but some other type of non-pertroleum-based film.

They claimed it made no difference to the sound of the disks.
