Perhaps, but the HP125 and HP150 Series I *used* 66.
I don't know
why, just that's what I found. Also, the HP125 8" drives used 66.
The inner (higher numbered) tracks were certainly less reliable in the
earlier drives.
Perhaps HP set some sort of reliability threshold, and stopped at the
point that their statisticians said was the max to perform [statistically]
to spec.
I saw multiple DIFFERENT upper limits (66 and 70) on discs (HP refused to
call them "disks") that were supposedly the same format.
