However, CD-4 did in fact have a stereo subcarrier containing rear channel

CD-4 which (for the benefit of some here of limited knowledge) , had
nothing to do with Compact Discs !

Interestingly there WAS a quadrophonic disc format in the Red Book standard.
I don't think anyone ever implemented it. It would have been much more useful
to put a mono format in there as well, for 148 mono minutes on a disc.
