Abstract:
1. A method of regulating a tracking of a scanning device of a drive for a storage medium, the method comprising: measuring a position of the scanning device with respect to the storage medium which has been inserted into the drive; comparing the position of the scanning device to a preselected position; controlling at least one actuator as a function of the comparison between the position of the scanning device and the preselected position, so that the scanning device is moved in a direction of the preselected position; measuring an external acceleration acting on the scanning device in one direction of movement of the at least one actuator; deriving a correction signal from the measured external acceleration; and sending the correction signal to the at least one actuator; wherein the at least one actuator is controlled by the correction signal, so that the at least one actuator counteracts the measured external acceleration acting on the scanning device, and wherein the at least one actuator is used as an acceleration sensor.
