Abstract

The present invention relates a record carrier (10) which comprises a predetermined area for storing pre-recorded data protected by an error correction format, wherein the error correction format defines error correction blocks each having a data block with a predetermined amount of data. The amount of data is set to a reduced value which leads to a coding efficiency smaller than 80%, so that the recording length (RL) of the error correction blocks is less than or equal to the circumferential length (L) of the recording track on which the pro-recorded data is stored. Furthermore, the present invention relates to a manufacturing method, coding method and coding device for the record carrier (10). Thereby, undesired overlap of data within one error correction block can be prevented in cases of small circumferential track lengths.
