Thanks for that Al. Never thought about humidity and mag tapes as
only time I used to backup data to 9 track tapes was in Vancouver
where humidity always high. Also used Time Shoppa's and Kevin
McGuigan's drives to extract data from those tapes in
Vancouver. Doubt I'll be copying any more of my mag tapes but will
definitely keep that in mind in case I do that in Kamloops where RH
quite low in winter. Have a humidity sensor in my guitar case as
have to moisten a sponge every few weeks to go in guitar so wood
doesn't crack. Can detect shrinkage of wood by increase in resonant
frequency of strings increasing as wood shrinks. Also take extreme
care when touching any non-TTL IC during winter here.

"George Dragner always wore a belt with a metal dragon buckle. He
was a colorful character known for pissing off management. His most
famous act was tossing a chair through the window at a customer
site. The customer refused to believe that the lack of humidity in
the room was screwing up his magnetic tape media. As the tape heads
depend on the moisture from the air to prevent the magnetic oxide
from being torn off the media from the friction during a rewind.
George broke the window to prove his point. He was right ! "
There is a minimum RH specified for tape, but "tape heads depend on
the moisture from the air" ??
