... the rotational frequency and angular position of 1) above, the DSP creates a rotating magnetic field. When the DSP receives this command, the DSP drives the voice coil motor, via the digital-to-analog converter and power amplifier, to move the head to maintain the detected rotational speed. 8.7.5... Voice coil motor control The voice coil motor is done by firmware by digital servo control using an analog-to the target cylinder. The DSP receives a position signal from a low rotational frequency up to move...
