I'm seeking a source for the specifications for
7-track tape
heads. I'm thinking what I really need is just the mechanical/
physical specifications... that leads me to the second part..
OK, a quick session with my calipers confirmed the spacing is the
same as 7 track instrumentation recorder heads (which are weird
two stack things with every other track on a separate head)
http://jcs.mil/RCC/files/xappxd.pdf for details.
from that spec:
track width .050" +/- .005
track spacing .070"
track tolerance +/- .002
track number
1 (reference) .000
2 .070
3 .140
4 .210
5 .280
6 .350
7 .420
