INFORMATION RECORDING MEDIUM AND INFORMATION REPRODUCING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an information recording/reproducing apparatus, etc. capable of improving reliability by evading deterioration in error correction capability and effectively utilizing storage capacity by reducing uselessness in a recording area in forming a linking area in the recording of added data in a recordable information recording medium. SOLUTION: An ECC block which is a unit of error correction for recording data is provided with a unit block area recorded so as to be divided into L (L is a natural number) frames to which sync codes are respectively added and a linking area inserted into a boundary part between adjacent unit block areas and including two frames to which sync codes different from the sync codes in the unit block area are added on positions having the same space as the sync code space in the unit block area. Sync codes of N
