moving the Swing Arms toward the outside of the deck plate.
The Supply Swing Arm is provided with a safety sw ,i tch which stops
the transport when the tape becomes unthreaded from the reel or
when too much slack develops in the tape pat h.
This roller prov id es tape guidance and helps iso ' late the heads from
variations in tape motion caused by irregularities in tape supply.
The tape motion causes this roller to rotate, which generates tach
pulses which are used to calculate tape time and tape direction .
The
Capstan Shaft is dir ec tly driven by a Quartz crystal Phase
Locked Loop controlled brushless DC servo capstan motor.
The tape is driven by the rotation of the Capstan Shaft against this
roller.
