Re: Could there be possibly a reason why a SHM-CD is better? Reply #25 – 2018-11-01 00:45:42 Hmm, my lazy read on Wikipedia (https://de.wikipedia.org/wiki/SHM-CD) reveals, that instead of using the regular polycarbonate, they use a more translucent plastic, normally used as the screen in LCDs.So higher transparency, so potentially SNR in the pickup system. Supposedly, the plastic is easier to work with when CD are stamped.That's the only change, compared to a traditional CD. Personally, my concern would be how good that plastic works with the reflective layer, and if they need a different glue, etc. Also, how scratch resistant is it. Granted, PC isn't the best when it comes to being resistant to scratches, but you can always go worse ¦DIt's nice that they managed to potentially improve CDs, while keeping them backwards compatible, but I don't think it really means anything in the industry. People don't really buy CDs anymore, so it's kinda pointless, I'd say.
