The invention relates to a motion control system for driving a motor-driven device precisely to a predetermined position in a short time. More particularly, this invention relates to a CD-carousel loader having a precise and short access to the next information medium. The object of the invention is to provide a motion control system for a platter of a CD carousel which requires little outlay and satisfies the requirements in respect of high positioning accuracy, short motion duration and self-locking. According to the invention, this object is achieved by means of a drive system comprising a motor driving circuit and a braking circuit having a common input terminal responsive to a pulse signal during a deceleration period in front of a predetermined position of the motor-driven device. The field of application of the invention is associated with apparatuses for the recording or for the reproduction of information with a device providing the scanning or recording system with the information medium by a platter of a CD carousel. |
