Melting the CD should work... but in practice that takes a specialized "oven" (I seriously doubt my home oven gets hot enough), and is likely to produce toxic fumes, and leave behind a sticky mess (stuck to the surface of the specialized oven).

For no adequately explored reason I've tried various ways of physically destroying CDs: - Hammer on hard surface: Leaves lots of little fragments, generally still stuck together by the protective coating. - Roasting over an open fire: Produces a Salvador Dali effect until they catch fire, then huge amounts of toxic smoke ("fulfilling our carbon tax quota" was one comment) and equally toxic-looking residue. - Propane torch: Melts them without producing combustion products. - Skilsaw: Melts them together at the cutting point, rest undamaged. - Axe: Like skilsaw but without the melting effect. - Using the propane torch and hammer to try and drop-forge a crude double- density CD: Messy.
