If I'm not mistaken, TK70 drive can read but not write TK50 tapes.

I hope to start backing up my MicroVAX 3800 soon via the TK70. Sounds like
8mm is more unreliable than the TK70, and I don't have but one
magneto-optical disk.
Are there any precautions I need to take before sticking a tape in the
drive? Pinch rollers that might be gooey?
