Abstract
Apparatus for scanning a rotating information carrier having mutually substantially parallel tracks for the recording of information. The apparatus includes a transducer for scanning the information carrier and for generating a position signal which indicates a position of a scanning point scanned by the transducer. The apparatus further includes means for rotating the information carrier about an axis and means for moving the scanning point in a radial direction with respect to the axis. The apparatus has a scanning mode in which the scanning point jumps both from one track to another in a first radial direction and from one track to another in an opposite second direction during reading or writing of a file.
