Abstract
A new actuator control technique for 8cm DVD-RAM drive, used for a video camera recorder was developed. The drive is required to record pictures without trouble in a situation that external disturbances occur when using portable equipment. However, the optical disc drive is easily influenced by disturbances, such as vibration or shock. The new technique consists of the Acceleration Feed Forward Control(AFFC)and the Velocity Feed Back Control(VFBC). Suppressing external disturbances made it possible for the drive to be used practically inside the video camera.
