Abstract: Provided are recording media, recording/reproducing apparatuses, and recording methods for use in long-term data retention. Recording medium information may be copied and stored in a new information zone in a data area. Accordingly, if medium recognition of a lead-in area and/or a lead-out area fails, a recording medium may be recognized using the data recorded in the new information zone.

Abstract: A data compensating method and apparatus for compensating a block from which data cannot be read due to the presence of a scratch or dust when reproducing an optical disk are provided. The data compensating method includes the steps of: (a) setting a first block region for storing a block of data currently being reproduced and a second block region for storing the previous block of data, and reproducing the disk according to a read command; (b) determining the type of data block from a header in a sought block when the number of seek operations is greater than a predetermined value in reproducing the disk in step (a); (c) substituting an address of a block of data in the second block region, corresponding to a data block determined in step (b), for an address requested by a host; and (d) transmitting to the host the block of data in the second block region substituted in step (c).
