Abstract: 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.

Abstract: A write-once disc includes: a plurality of update areas in which a predetermined kind of updated information is recorded; at least one main access information area in which main access information is recorded, the main access information indicating a final update area in which finally updated information is recorded among the plurality of update areas; and at least one sub access information area in which sub access information is recorded, the sub access information indicating a location of the finally updated information recorded in the final update area. Accordingly, an access time for reading a predetermined kind of information required to use the write-once disc can be reduced.

Abstract: An optical recording medium having a read-only storage area and a writable storage area and a recording/reproducing apparatus and method therefor. The optical recording medium is a hybrid disc having both the read-only storage area, which is suitable for mass production of information having the same contents, and the writable storage area on which data can be recorded, updated or added at a user's option.

Abstract: A method and apparatus recording and/or reproducing data on/from a write-once disc, and a write-once disc therefor, the write-once disc having at least one recording layer including: a plurality of update areas in which predetermined updated information is recorded; and at least one access information area in which access information indicating an update area in which final recorded updated information is recorded. Reducing access time for reading the updated information using a location of predetermined updated information. Also, when a plurality of update areas for writing updated information required to use the write-once disc exist, a recording apparatus or a reproducing apparatus can quickly and easily determine an update area in which final updated information is recorded among the plurality of update areas.

Abstract: To provide write protection of a disc in a bare state that is usually used in a cartridge having a recognition switch for write protection, such as a DVD-RAM, write protection information is recorded in a Lead-in area, a Lead-out area or a recording information area other than a user data area of the disc, and the data is protected from unwanted overwriting or erasing using the write protection information. Even when the write protection information stored on a disc does not match the state of a recognition switch of a case for write protection, the data can be prevented from unwanted overwriting or erasing. Thus, write protection can be ensured when a recordable and/or rewritable recording medium, such as a DVD-RAM, a DVD-R or a DVD-RW, is used in a bare state.
