Abstract
An optical apparatus for scanning a tape-shaped record carrier, which apparatus uses a mirror polygon for scanning tracks extending perpendicularly to the tape travel direction. Since at least one facet, or a part thereof, of the mirror polygon extends at a different angle to the axis of rotation, the scanning spot is periodically moved transversely to the track direction, so that a tracking signal can be generated.
