These used the 12" tape mats. I was wondering if that was them in the photo.
  We recorded IDs, PSAs and had several songs recorded on them because we didn't
have cart machines. I though they were pretty cool and they worked quite well.

   The reason for the high "tape noise" was because the "tape" grains were
randomly orientated.  Had they used FM it could have been much cleaner.
