(3) Spindle motor
The disks are rotated by a direct drive Hall-less DC motor.
(4) Actuator
The actuator uses a revolving voice coil motor (VCM) structure which consumes low power
and generates very little heat. The head assembly at the edge of the actuator arm is controlled
and positioned by feedback of the servo information read by the read/write head. If the power
is not on or if the spindle motor is stopped, the head assembly stays in the specific CSS zone
on the disk and is fixed by a mechanical lock.
