    摘要: A disc defect management method and apparatus using a defect management area that can be updated, and a write once disc incorporating the method. A data area is disposed between a lead-in area and a lead-out area. The disc includes a defect management area (DMA) that is present in at least one of the lead-in area or the lead-out area, wherein defect information and defect management information are repeatedly recorded in the DMA according to a recording operation. Accordingly, the disc defect management method and apparatus enable effective use of the defect management area. The method is also applicable to a multi layer disc having a user data area on each layer. The defect information and the defect management information for an individual defect may include cumulative defect information and defect management information related to previously identified defects.

    摘要: A reproducing apparatus is provided. The reproducing apparatus includes a recording/reading unit that records data on or reads data from a disc including a defect management area in which defect information regarding data recorded in a data area of the disc and defect management information for managing the defect information are repeatedly recorded, and a controller that controls the recording/reading unit to read the defect information and the defect management information from the defect management area, and read data from the disc using the defect information. First defect information, which is repeatedly recorded, includes second defect information which is recorded in a predetermined area and defect information regarding a defective block occurring after the second defect information is recorded. The defect management information includes location information of the defect information.

    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.
