"Redbook" meaning?


What is the origin of the word "Redbook" cd's.
zippyy
The book that Philips/Sony put out with the format's specifications originally had a red cover.
What is interesting to note here is Philips declaration that the new copy protected cds are no longer redbook cds but something else and must be marked as such.....
i've been led to believe that the term derives from the followers of chairman mao, who were able to copy illegally very early cd's, whilst simultaneously memorizing passages from the "little red book." -cfb
