SileEeles Posted April 7, 2015 Report Share Posted April 7, 2015 This has be floating around my mind for a few days now, and ive looked at all the discs I own (around 80-ish) and I cannot figure out what the difference is between shock absorbing mechanism discs, and ones that aren't. They look identical to me, bar obvious differences such as colour, brand, etc. What I mean is the plastic housing itself. What makes the shock absorbing ones different? Or is it some strange marketing thing? Quote Link to comment Share on other sites More sharing options...
AVITWeb Posted April 7, 2015 Report Share Posted April 7, 2015 If I am remembering correctly, it has to do with a different coating on the disc itself. It really isn't a different "mechanism" so to speak. The normal colored discs from Sony say "SA Coating Advance" assuming Shock Absorbtion. I can only assume a better coating on the gold discs. Again...If I am remembering correctly. Quote Link to comment Share on other sites More sharing options...
eriktous Posted April 8, 2015 Report Share Posted April 8, 2015 I thought it was that black liner you can see along the edge of the housing. I think it's intended to keep it seated firmer inside the machine and reduce outside vibrations being transmitted to the disc. Quote Link to comment Share on other sites More sharing options...
SileEeles Posted April 8, 2015 Author Report Share Posted April 8, 2015 the black liner is nothing at all as far as I know, its just a visual part of the plastic casing. I could be wrong however. Most other discs dont have this, though, but do say Shock Absorbing Mechanism on, so one would assume it is something else. The main theorys I have heard is the coating on the disc, which has been mentioned, or the discs being slightly thicker in some brands.

freddyjollo Posted April 8, 2015 Report Share Posted April 8, 2015 sounds to me like a pr/sales ploy? like cd perfect sound probably was better than average quailty control of the discs so they dont wobble so much due to thickness or circularity variation Quote Link to comment Share on other sites More sharing options...
eriktous Posted April 15, 2015 Report Share Posted April 15, 2015 Noticed this auction on eBay which has a clear picture of the backside of some sealed discs with Shock Absorbing Mechanism and the picture shows the black liner I mentioned in my previous post as (part of) this mechanism.
