Subject:      Re: 3M Security System & computer disks

We had the same questions so, being a Minnesota library, I got on the
phone last year and called down the road to talk to the folks at 3M.
They assured me that the security gate will cause no harm to disks,
tapes, videos, laptops or anything.

The only thing that is a problem is the sensitizer/desensitizer
equipment.  Do not run any of the above through the desensitizer.  That
would wipe out the magnetic disks, tapes and videos.

Because of this we used to put bright pink warnings on the covers of
all our books that had disks or CD's in a back pocket with a warning
to remove them before desensitizing or sensitizing the books at check
out.  Recently, we decided to remove them ourselves and store them at
the reserve desk, leaving a note in the book informing patrons where
the disks are.

Donna,
The only way disks get wiped is when they are "desensitised" on a
book desensitisor, which is occasionally done accidently, also audio
tapes. We don't really have the problem of students walking through
with them above their heads, although they can put them a bypass
shelf or give them to our Library Attendant on the door.
Hope this is useful.
