"RL01/RL02 Technical Manual"
on page 58, it shows upper head (1) and lower head (0).
But,
http://www.bitsavers.org/pdf/dec/disc/rl01_rl02/RL02techDescr.pdf
throughout refers to the upper head as 0 and the lower as 1.
I don't know the answer, but I certainly see the confusion.
A later revision (-002) of that manual updates the Figure 1-6 on page
I/1-9 and explicitly labels the heads upper (1) and lower (0) while
retaining the text throughout that refers to them as the opposite of
that. Interesting and confusing!
I guess you'll have to measure to find out.
