It did... but then I've been teaching that kind of stuff to students for over twenty years now! ;-)
I would love to know what politking went on to keep the MDisc out of car audio?
I don't think it did. MD was a hugely popular format in the US and Japan, and there were a great many in-car MD players. It just never really caught on that well in the UK.
The format is so obviously better suited having intrinsic protection.
Absolutely. The manufacturers learned from the mistakes of the CD format. They thought the biggest problem with CD would be dropouts due to pin-holes in the mirrored layer, so that's what they optimised the error protection system to deal with. However, the mirroring was quickly perfected and the real issue was deep surface scratches and optical contamination (grease etc) which caused mistracking and defeated the error protection systems. Encasing the disc in a plastic box removed those risks very effectively.
