There appear to be different kinds of material used
for the rollers.
For instance, with a 1999 OnStream DI30 (parallel port 30gb) ADR
drive, it's a typical black rubber roller like you'd see in many QIC
drives, and it's turned completely to goo.
So at least one type of rubber liquifies, and at least
one type
hardens and cracks.
Off the top of my head, I recall that the Archive multi-cartridge
(changer) drives were the worst--the turning-to-goo rubber is used in
several places and creates a sticky mess that's almost impossible to
clean completely.
HP drives seem to be pretty durable, however--and I've had good luck
with Sony drives as well.
