(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.
