Try 
tar xvf ./thefile.tar /usr/thedirectorystore

(I am assumeing ./thefile.tar is actually /dev/st0 or some
other tape device??)

note: I leave off the '-' - tar is an ancient program and doesn't need them ;)
its just how I learned to use it ;)


Why don't you just do this (I am assuming /dev/st0 is your tape device...
if it isn't then substitute it for what I use here)

cp /dev/st0 thetarfile
{switch tapes}
cp thetarfile /dev/st0
{switch tapes}
cp thetarfile /dev/st0 

I THINK that should work.
