I read:
I think, but Chris could explain better, that the time
is calculated
just from the speed of the record. With a rising saw like this

actually you explain it just great ;)
you could just count the zero crossings per second and
take the ratio
compared to the expected 440 Hz. It's simple math. Time encoding to
get data about how far from the rim the needle is, would be impossible
this way, unless you change the saw's frequency in a complex way...
and the rising saw gives me the direction info of course,
