I remember CD caddies :)
I recall back at secondary school in my first
year there (year 7 for UK'ers), in 1990/1, that
the new computer in the library used CD's
which were in see through plastic.
Essentially the "CD" of the time was like
floppy discs - the writable media (medium?)
was encased in protective plastic shell.
Sounds like the Philips 1x speed CD that was used by DEC as the
RRD40. It took standard CD-ROMs but they were inserted in a plastic
shell because the drive had no tray or any other means of supporting
the CD.
My own RRD40 caddies are 250 miles away but I've got a drive at work
:)
Mine are right here but you've saved me the bother of photographing
an example (the bit that pulls out was called the "antlers"
apparently).
I would have thought that seven years ago the RRD40 was already
a distant memory. (Its predecessor BTW was the RRD50 which was
a tabletop unit top-loading CD-ROM that was _slower_ than 1x!)
In a school in 1990 I would guess that this is just the
standard "flip-top" lid caddy that many early CD-ROM units
used. I can see ten of them over to the left; I could take
a snap of one of those too but there must be gazillions
on the net already.
Indeed here is one:
