Hi,
Also, I've been told that you could
"compact" the tape by breaking the
reel with your finger while formatting (writing timing and mark tracks).
I'm guessing that electromechanical differences between drives would
influence the actual speed of the reel and therefore the usable size of
the tape.
The reel speed is determined by a 40Hz timing circuit in the drive. The
motors run with synthesized AC. The timer is adjustable.
For me it sounds quite more interesting to format a tape on a normal
drive - and then use it on a drive which has been adjusted to spin
faster... :-)
Regards,
