Note: Retract circuit sometime will be malfunctioning by means of negative voltage on the terminal

VCMREF (pin 52) in the following sequence.
If you want to countermeasure this, you need to avoid the following sequence or to attach the

Schottky Barrier Diode (SBD1) between terminal VCMREF and GND. (see figure 2)

1. Spindle motor driver is active and VCM driver is disable by (VPCNTL = Middle).

2. Power supply goes to low level after above condition 1 and retract circuit becomes active by
