A device for scanning a first and second type of optical record carriers generators a first and a second radiation beam for scanning the first and second type of record carriers, respectively. Each of the series of reproduction zones for the 120\xd7 speed, the series of reproduction zones for the 60\xd7 speed, and the series of reproduction zones for the 30\xd7 speed, each reproduction zone of which is for the reference time interval, is so set as to be free from overlap with the other series of reproduction zones. If the identifiers match, the configuration is used for communication.
