ABSTRACT:
A device for recording information writes marks in a track on a record carrier of a re-writable type. The device records the information according to a predefined recording format like DVD for constituting a recording area containing user data preceded by a lead-in zone. The device has a formatting unit (36) for formatting the record carrier. First it is detected if the record carrier has been recorded before. If so, a size is determined of a pre-existing contiguously written area that extends from the beginning of the recording area. The formatting includes writing data on the record carrier indicating that the recording area does not contain user data. Formatting status information is provided on the record carrier indicating the size of the pre-existing contiguously written area.
