The pickup assembly possesses as many as 12 2-phase stepping motors of magnetic exci-

turned on/off and its direction of rotation is controlled by pulse signals from the DC control-
ler PCB.
The following table shows each motor used in the pickup assembly, and the figure that
follows it is a block diagram of the pickup motor control circuit for the cassette 3/4 by way
