I wonder if LP problems arise because the capstan controller can't
keep the speed within such tight (percentage) limits at LP at it does
at SP? On the other hand, at LP the drum would have to rotate at a
lower speed too, so the voltages induced in the heads should
theoretically be significantly lower, (flux change/unit time reduces),
and if the induced head voltages approached the "not permitted"
voltage levels (in the threshold area between a 0 and a 1), then you
would get a rubbish data stream off your tape that no amount of error
correction will fix.
Hypothesis and conjecture, of course. Needs someone with a bit more
cam knowledge to contribute.
Thanks for assistance Gary,
Regards,
Hughy
