At some  point in the future the archive I work for may have to deal with 
hundreds,  perhaps thousands, of helical audio recordings made in Alaska 
using  Soundscriber SS-124s (helical recorders which capable of recording 
24  hours on a 2 inch tape medium). When we conducted a brief and spotty  
inspection a couple of years ago of the tapes, recorded in the early  
1960s, now stored a warehouse without climate controls, we found that  
many of the tapes showed signs of de-lamination; the oxide coating is  
flaking off of the base of many tapes. I'm trying to get ahead of the  
curve and was wondering if anybody here could point me to literature, or  
offer advice, on consolidating magentic audio tape oxide  coatings?

Thanks in advance.
