Talk:Compact disc

In my opinion, the discussion about disc vs. disk is a moot point because "compact disc" is a tradename not a generic name.

History, please! When was the CD created, 1983? CD-R, early 1990s? And the CD-RW? And how about a link to a more generic entry on data storage? Further, how did the engineers decide on the diameter? Was it to match the 5.25" floppy disks common in the early 1980s? Or was it to have enough room for an hour of music or for Beethoven's 9th Symphony?
