摘要： A method of determining whether a defect exists on an information storage medium is provided along with a recording/reproducing apparatus using the same. Such a method comprises: seeking a defect entry whose state information indicates that a defect block or a replacement block has been re-initialized without certification from a defect list for managing an information storage medium and including state information of the defect block and state information of the replacement block, wherein the medium includes a spare area for recording the replacement block to replace the defect block occurring in a user data area on the medium; and certifying the defect block or the replacement block registered in the sought defect entry. As a result, defect information can be effectively rearranged for quick re-initialization without certification in order to improve the performance of a drive system.

摘要： An error correction block having an extended format compatible with a standardized format of a conventional error correction block, a method and apparatus for generating the error correction block, and a method of correcting an error using the error correction block. The method of generating an error correction block includes adding extra parity information for error correction to input data which is of a smaller size than main data of a standardized reference format, thereby generating an extra error correction block which is the same size as the main data, and generating an error correction block complying with the reference format using the extra error correction block as the main data.

摘要： A write once disc allowing management of a data area, a method of managing the data area of the write once disc, an apparatus recording data on the write once disc, an apparatus and method of reproducing data from a write once disc. The write once disc, includes a lead-in zone, a data area, and a lead-out zone. The write once disc includes a predetermined area storing area allocation information which indicates whether at least one section of the data area is allocated for disc defect management. In the disc and method, area allocation information specifying a structure of the data area is recorded on the disc, thus allowing a recording/reproducing apparatus to recognize the data area structure. Therefore, allocating areas, such as a spare area, for disc defect management other than an area for storing user data, to the data area is possible. The allocation of the areas for disc defect management to the data area enables effective use of the write once disc.
