An information recording medium to which data extra ECC is applied, and a method and apparatus for managing the information storage medium is provided. The method includes: determining whether extra ECC is applied with respect to data that is to be recorded on the information recording medium, and deciding an extra ECC application rate; assigning an area for recording a data block including an extra parity generated by applying the extra ECC to the data that is to be recorded on the information recording medium, to the information recording medium; assigning an extra ECC management information area for recording extra ECC management information for managing the extra ECC, to the information recording medium; and recording or updating the extra ECC management information in the extra ECC management information area. Therefore, it is possible to improve reproduction reliability while maintaining reproduction compatibility with conventional apparatuses.
