Abstract
Disclosed is an arrangement for reading an information carrier, comprising a read head for scanning the information carrier along a scanning path and thereby generating one or more electrical signals in response to a pattern recorded along the scanning path; a signal processing unit for processing the one or more electrical signals; electrical conductors for conveying the one or more electrical signals to the signal processing unit; characterized in that the arrangement further comprises controllable termination means for terminating at least one electrical conductor with a selectable impedance, the controllable termination means comprising at least two impedances and selecting means for selecting an impedance to terminate the at least one electrical conductor. The controllable termination means can select one of the at least two impedances. This makes the arrangement according to the invention capable of tuning to varying circumstances. If for certain circumstances a high impedance is needed, then a high impedance is selected. The varying circumstances can, for instance, be the speed at which the information carrier is rotated or the type of read head that is used.
