Re: [ARSCLIST] Distance between staggered heads

[Mwcpc6@xxxxxxx]

One format that has always puzzled me was the early Brush Soundmirrors that  
used a half track positioned in the middle of the tape. Was the idea to reduce 
 the effects of poor tape guiding at the expense of fringe effects?
 
A side effect of this is that when exploring a batch of paper based tape  
that had been reused on half track machines, I was able to recover the original  
recordings, mostly McCarthy-Army hearings and radio dramas, by positioning a  
quarter track head to read between the two newer tracks.
 
How often do archivists check for residual recordings of this kind on tapes  
of this vintage? There could be interesting stuff there.

What was the oddest track format or  spacing for an audio tape
you have run into so far ? Just curious... I know  that instrumentation
tapes are a different animal, but I wondered about  audio tape formats. I
am familiar with many of them myself, but you have  more exposure to the
old and odd than I  do.
