Patent ID: 7541606

Claim:
A method for processing information carriers in which an information carrier and/or a container, in which the information carrier is located, is processed by being moved and/or fixed, by at least one mechanical processor, the mechanical processor being driven by at least one stepper motor that rotates with a rotation speed and a torque, and information from the information carrier being read out and/or written in the information carrier, the method comprising: recording a motor load which is a measure for the load of the stepper motor while the mechanical processor is being driven, deducing information about a position of the processor from a number of steps, which corresponds to the number of steps of the stepper motor while the processor is being driven, taking into account the motor load recorded and controlling the stepper motor in response to information deduced about a position of the mechanical processor, and reducing or increasing the rotation speed and/or the torque of the stepper motor when the position of the mechanical processor lies within pre-specified positions.
