I'm pretty sure the 18-disc model just used three six-disc caddies.
On another note: my parents still use a home CD player from Pioneer that uses this same caddy. Probably bought it in 1989 +/- 2. (Yeah, if I weren't at work, I'd have just used Opt-Shift-= to get the proper +/- sign. I did hit Win-Shift-=, only to discover it just printed +.)
