Hi Parker:

Back when I had regular contact with a large record company's reissue/archive people, they told me 
that most of the tapes in their library were on hubs because they felt reels posed a risk to the 
tape. I never understood exactly what risk they envisioned with aluminum reels, but that was their 
practice. In my own practice, I'm not a big believer in hubs. I have plenty of reels and anything 
important, valuable or fragile is on a metal reel. What I have done over time is get rid of metal, 
slotted hubs, simply unscrewing the flanges and replacing with modern fiberglass unslotted hubs.

Jerry, if your tapes are old non-backcoat, or sloppily wound backcoat, Parker brings up a really key 
point. Transit can rattle even a well-boxed hub just enough to make the tape pack impossible to get 
out of the box and onto a tape machine without disaster. If it were me, I would buy flanges and 
screws/sex nuts before shipping.

One more thing. I'm not sure I'd keep anything important long-term on plastic NAB reels. Question 
is, if you have fragile non-backcoat tape and only a plastic reel available, do you store it on the 
plastic reel?
