By now we all (hopefully) know that lasers are used to read signals from CDs and videodiscs, but last weekend while visiting friends over Christmas I heard of a new application for the same (or similar) technology: reading good ol' vinyl records by contactless laser pickup. Has anyone here heard of this, and can anyone provide any details on HOW it is being done? This is one of those ideas that, to me, seems obvious in retrospect, and "it's a wonder nobody thought of it sooner." Chris Chiesa Chris_F_Chiesa@cup.portal.com
