CD is an amazingly robust consumer sound medium. The Eight to Fourteen Modulation (EFM) and Cross-Interleaved Reed-Solomon Code (CIRC) error detection and correction methodologies mean most errors can be detected and corrected without anyone ever noticing. That said, there’s just some poorly pressed CDs out there that time has been unkind to. A lot from the Philips and Dupont Optical (PDO) plant in the UK have suffered from ‘bronzing’ and may be unplayable now. But LaserDisc is a different story where many problems have occurred with disc readability (no error detection and correction as it’s actually analog video read by laser) and ‘rot’ due to poor manufacturing—I’m looking at you DADC, Terre Haute, Indiana!

Would FSM replace a defective disc for an in-print title like Body Heat? Disc #2 seemed to be working fine in my set. Sorry to hear about your problems with defective discs Mr. Jack. You ought to contact SAE regarding Body Heat. I recall there was some concern about some of the copies of Outland, and I thought Lukas assured us that defective discs would be replaced, even if they had been bought a while ago.

To be honest, the only real answer to media decay is high definitition digital stored on multiple hard discs and copied to new hard discs from time to time. I agree with a previous poster, I expect a perfectly made CD to outlast me, but it only takes a minor defect undetectable at purchase time to start a rot that might not show up for years. I still prefer to buy a CD than to download, and I prefer to download than to rely on streaming services, where I have no guarantee of perpetuity at all. But I automatically rip my CDs lossless, and I have a main hard disc library, a backup hard disc library, and a Cloud copy library, and I replace my hard discs every few years. That's the best bet you'll ever have of insuring yourself against media decay, or indeed other risks such as fire, flood, burglary, whatever. Cheers
