Abstract :
A new actuator control technique for an 8 cm DVD-RAM drive, used for a video camera recorder, was developed. The new technique consists of the acceleration feed forward control (AFFC) and the velocity feed back control (VFBC). Suppressing external disturbances, such as the vibration or the shock made it possible for the drive to be used practically inside the video camera
