Per Wikipedia (consistent with my faulty memory):

"The Compact Disc reached the market in late 1982 in Asia and early the 
following year in other markets."

The same source reports:

"The first hard disk drive was the IBM 350 Disk File, invented by 
Reynold Johnson and introduced in 1955 with the IBM 305 computer."

Here, I can attest that as of Summer 1957, the state of the art in 
practice was the 4K drum memory of the IBM 650.

I did not have a CD pressed until 1996, but at that time the broker 
still handled Exabyte tape - the format he reported to have been used 
frequently before CD-R and Jaz came into use.
