wherein the text sub data units are at a location on the recording medium identified by the linking information and that is different than a location of the navigation information file.

13. The recording medium of claim 8, wherein if the coding information is related with an Electronic Music Distribution (EMD) file, the coding information does not include text data related information, and if the coding information is not related with the EMD file, the text data is processed based on the coding information.

19. The apparatus of claim 13, wherein if the coding information is related with an Electronic Music Distribution (EMD) file, the coding information does not include text data related information, and if the coding information is not related with the EMD file, the text data is processed based on the coding information.

14. An apparatus for recording text sub data, comprising:

a pickup configured to record data;

a controller configured to control the pickup to record a main data on a recording medium;

to record a plurality of individual text sub data units included in text data to be presented with the main data on the recording medium, the text sub data units being separated from the main data;
