ABSTRACT:
A method is provided for regulating the tracking of a scanning device, for example, a read/write head, of a drive. A drive for storage media having a scanning device is also provided, permitting improved regulation of the positioning of the scanning device. A measured position of scanning device with respect to a storage medium inserted into the drive is compared with a preselected position. Depending on the result of the comparison, at least one actuator is controlled so that the scanning device is moved in the direction of the preselected position. Acceleration acting on the scanning device is measured in a direction of movement of at least one actuator. A correction signal is derived from the measured acceleration and sent to the at least one actuator, the actuator being controlled by the correction signal so that it counteracts the acceleration acting on the scanning device.
