APPARATUS AND METHOD FOR SCANNING A ROTATING INFORMATION CARRIER

摘要

An apparatus for scanning a rotating information carrier (1) having mutually substantially parallel tracks (2) for the recording of information. The apparatus includes a transducer (5) for scanning the information carrier and for generating a position signal (Id) which is indicative of a position of a scanning point (6) scanned by the transducer (5). The apparatus further includes means (4) for rotating the information carrier (1) about an axis (3) and means (7-12) for moving the scanning point in a radial direction with respect to the axis (3). The apparatus has a scanning mode in which the scanning point (6) 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.
