Abstract
A recording format on a recording medium comprises a data portion (4) in which a data train should be recorded. The data portion (4) comprises a user data portion (44 and 47), a check data portion (45) and resynchronizing pattern portions (46). The data train is divided into m or 4 code words, each code word being n=148 bytes. The resynchronizing pattern portions (46) are added to the data train for every m.times.3=12 bytes of data to be recorded, and serves to recover data synchronization in the event that data synchronization is missed. Each code word having a check data portion (45) is capable of correcting errors of T bytes, and errors generated in each code word by missing of data synchronization can be corrected.
