    摘要: A data recording and/or reproducing apparatus and method for an information recording medium includes: an extra ECC encoder; and an extra ECC controller determining whether extra ECC is applied to the information recording medium, and controlling the extra ECC encoder to generate an extra parity data block corresponding to data that is to be recorded on the information storage medium. The extra ECC encoder includes: an extra parity generator generating an extra ECC data block based on data that is to be recorded on the information recording medium, performing ECC on the extra ECC data block, and generating at least one extra parity. An extra parity interleaver interleaves the at least one extra parity and generating the extra parity data block.

    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.

    摘要: A computer readable medium, apparatus, and method for efficiently managing a space bitmap. A computer readable medium includes: a user data area on which user data is recorded; and a temporary disc management area on which a space bitmap indicating a recording status of recording and reproducing unit blocks of the user data area is recorded. The space bitmap includes header information for distinguishing an additional space bitmap from the space bitmap. The additional space bitmap is assigned when a space provided for the space bitmap is insufficient to represent the recording status of the recording and reproducing unit blocks of the user data area.

    摘要: A method of overwriting data in a write-once information storage medium and a data recording and/or reproducing apparatus provided for overwriting data in such a write-once information storage medium. In the data overwriting method, a command to overwrite new data in a first area of the write-once information storage medium where data has already been recorded is issued. Then, the first area is considered as a defective area, and the new data is recorded in a second area. Thereafter, updated defect management information, including information about the locations of the first and second areas, is recorded in the write-once information storage medium. Accordingly, overwriting can be performed in write-once information storage media, which is incapable of physical overwriting, by using a logical overwriting technique. Thus, data recorded in the write-once information storage medium may be changed or updated.

    摘要: A recording method, a host apparatus, a recording and/or reproducing apparatus, an optical recording information storage medium, and a computer readable recording medium storing a program for performing the method of recording. The method of recording data on a disk includes: when new data is desired to be recorded on the disk, at an address at which data is already recorded, updating a defect list by writing in the defect list defect information of the address at which the data is already recorded; and transmitting to a recording and/or reproducing apparatus the updated defect list and a command to record the new data at the address at which the data is already recorded. According to the method, overwriting is implemented on a write-once medium and furthermore, when this overwrite is implemented, the load on the drive system is reduced.
