A record carrier of a read-only type has information in a track. The information is subdivided in addressable blocks and a number of blocks constitute an information unit. The information unit is the minimal unit for error correction according to a format for writable record carriers. On the read-only record carrier a linking area is provided between information units. This has the advantage that compatibility with recordable record carriers is improved.
