    摘要： An information recording medium, on which when a spare area for a replacement block for replacing a defect block created in a predetermined area of an information recording medium is enlarged or newly allocated, defect status information of blocks within the enlarged or newly allocated spare area is changed and written on the information recording medium. By managing the defect status information of the blocks within the enlarged or newly allocated spare area, unnecessary operations of a drive system are eliminated thus improving efficiency of the drive system.

    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： A recording method for use by an apparatus and/or which is encoded on a computer readable medium includes selecting a defect management on mode or a defect management off mode that indicates whether defect management is to be performed or not while data is recorded in the recording medium, recording the data in the recording medium while defect management is performed on the recording medium, if the defect management on mode is selected, and recording the data in the recording medium without defect management, if the defect management off mode is selected.

    摘要： Replacement data for updating data recorded on an information storage medium is recorded in an area for logical overwrite (LOW) replacement; replacement data for replacing a defect generated on the medium is recorded in an area for defect replacement; and, if a defect is generated in an original block recorded in a predetermined area of the medium during a read-modify-write (RMW) process for a LOW for at least partial data of an original block, a replacement block replacing the original block is recorded in the area for LOW replacement and a defect list (DFL) entry including location information of the original block and location information of the replacement block is generated to indicate the replacement state.
