I used to be worried about this kind of disc loading mechanism too, but not anymore. Haven't noticed any problems w/ our car's CD player for instance -- and they pretty much all use this type. Yeah, it *looks* like it'd be less safe than the old tray mechanism, but I've had the old tray mechanism leave a scuff ring on a couple CDs in the past too just from how a disc could still be spinning when it's dropped into the tray inside the player.

Not saying the old tray mechanism is bad since that didn't really happen *that* often, but I don't think it's really all that much better, if at all. At least now I don't have to worry about my kids accidentally bumping into the tray and breaking it while it's extended out -- that happened to a previous DVD/SACD player I had.
