Mi OUTLINE OF THE DIRECT DRIVE MOTOR SYSTEM
The capstan motor is actuated by the DD motor digital servo system. The FG pulse is generated after the
detection of the zero crosspoint, and the reference signal generated from the quartz oscillator is compared with
this FG pulse. From this comparison, the accelerated and reduced speed pulses are generated, causing the
driving coil to function.
