[net.analog] Mag tape shielding

burns@iuvax.UUCP (01/14/85)

The following query was posted Dec 18 to net.video, but, receiving
no responses from this lively net, I suspect that it may have dropped
into a black hole.  Ergo, I am reposting it.  In hopes of generating
a reply this time, I am also sending this out on net.analog.
Surely this question is not too tough for you EE types out there? :-)

I am having a cabinet built to hold a 25" TV, VCR's, assorted video
equipment and tapes.  I have recently been warned that storing video
tapes within a foot of the monitor is unwise as it may slowly erase
the tapes.  Since the current design has only about 5" separation
from the bottom of the monitor to the top of the tapes, I'm concerned.

It would be difficult (expensive) to modify the design at this point.
Question: is there an effective technique for shielding the tapes from
the offending magnetic source?  
    Thanks,
