Re: [ARSCLIST] Effect of vibrations on audio tape

[Alan Lewis <AlanFLewis@xxxxxxx>]

One related problem I've observed is building vibrations causing tapes to  
"walk" on their shelves - to the point of being about ready to fall on the  
floor unless they were pushed back periodically.  I found  this with 
videocassettes in plastic cases on the top floor of a university  library building.  There 
were low frequency vibrations coming  from the HVAC system's air handling 
units in the attic causing the  upper part of the building to shake ever so 
slightly but strong enough to  make the smooth plastic cases move on their smooth 
steel  shelves.

Has  anyone had the experience of having an audio collection, and studio
&  equipment, next to a rail line (train, subway, etc)?  What  problems
did you have?  What, if anything, were you able to do to  minimize them?

There's a proposal for a light-rail line to come down  the street in
front of our building.  We have our audio tapes stored  in a basement
vault area, and our digitization rooms are on a floor about  10 feet
below street level.
