Apparatus and method for use in recording and reading edit data pertaining to reproduction of information signals and/or portions thereof recorded on a record carrier. Edit data includes skip information (identifying information signals and/or portion thereof for which reproduction is undesired) and/or restore information (denoting invalid skip information). The edit data enables determination as to which information signals and/or portions thereof should be inhibited during reproduction.

An optical scanning device can scan two types of record carriers each having a transparent layer with a different thickness, in which a radiation beam scans an information layer of the record carrier through the transparent layer. When scanning a first type of record carrier the best focus of a scanning radiation beam is positioned on the information layer and when scanning a second type of record carrier the paraxial focus of the radiation beam is positioned on the information layer.
