Re: arsclist Transfer of multiple copies, was: Full 3-D mapping of groove?

If you are working from a full track mono and are willing to give up a bit
of signal to noise, you could use a two-track stereo head.  This assumes the
gap is wide enough to allow independent reading of the separated sections
with sufficient data to effect the appropriate adjustment..
