Does anyone know the tracking angle of the
embossing needle on the RCA Home Recording
machine? I would imagine the ideal would be
perfectly perpendicular the the disc surface.

I acquired two needles, one has a yellow
shaft and one has a red shaft.  The yellow is
has a much larger tip.  What was the reason
for the two different sizes - was one for recording
and the other playback?

Thanks for any help.
