when i use a CDR to save data and then want to throw it away, i simply scratch the top surface, with a screwdriver or a pair of scissors, in a radial way from the center to the rim, removing a nice chunk of the reflective layer + dye + coating (laquer). a streak a few millimeters wide. that destroys the CDR just fine.
now that i start using DVDs, how to you kill a DVD? simply scratching it won't help because there's a polycarbonate later on both sides.
anyone has a simple, quick, effective and cheap method to kill those DVDs ?
