    • The present invention relates to an optical recording medium and optical recording medium record/playback apparatus and method, for managing defective areas in a rewritable optical recording medium. Particularly, the present invention adds a linear replacement control (LRC) bit to a secondary defective list (SDL) entry to discriminate a defective block information that is listed at the SDL entry according to a linear replacement algorithm from a defective block information that is listed at the SDL entry according to a skipping algorithm. This allows the optical recording medium record/playback apparatus to transmit correct information to a host. Furthermore, when a defective block requiring a new replacement block is found while recording or playing back data when the spare area is full, instead of carrying out the linear replacement, the LRC bit is set in the SDL entry along with the location information of the defective block to indicate that the corresponding SDL entry was made when the spare area was full, whereby data is not written in the defective block or data of the defective block is not read when rewriting or reproducing the data afterward. Consequently, the present invention can provide efficient management over the optical recording medium.
    • 本发明涉及一种用于管理可重写光记录介质中的缺陷区域的光记录介质和光记录介质记录/重放装置和方法。 特别地,本发明将线性替换控制(LRC)位添加到次要缺陷列表(SDL)条目,以根据列出的缺陷块信息根据线性替换算法来识别在SDL条目中列出的有缺陷块信息 根据跳过算法在SDL条目处。 这允许光记录介质记录/重放装置向主机发送正确的信息。 此外,当在备用区域满时记录或重放数据时发现需要新的替换块的缺陷块,而不是执行线性替换,LRC位与SDL条目的位置信息一起被设置 指示当备用区域已满时进行了相应的SDL条目,由此数据未写入缺陷块中,或者在以后重写或再现数据时不读取有缺陷块的数据。 因此,本发明可以提供对光学记录介质的有效管理。
