ABSTRACT:
A system includes a self-servo-write (SSW) module and a control module. The SSW module generates servo signals and a control signal. The control module generates a first current to bias an actuator arm against a spring when the control signal is received and discontinues the first current to release the spring and accelerate the actuator arm when the SSW module generates the servo signals.
