    摘要： To record video data or audio data on an optical disc on which a defective area exists, there is a method of determining an allowable number of defects in proportion to a recording size and skipping the defective area to use an adjacent area thereto. This method has a problem that the size of the recording area becomes larger by an equivalent of the skipped defective area so as to take a longer time for recording a file, and so convenience for a user is damaged. The size of the defective area allowed in a recording area is limited regardless of the size of the recording area.

    摘要翻译： 为了在存在缺陷区域的光盘上记录视频数据或音频数据，存在与记录尺寸成比例地确定允许的缺陷数量并跳过缺陷区域以使用相邻区域的方法。 这种方法存在的问题是记录区域的尺寸变得相当于跳过的缺陷区域，从而需要更长的时间来记录文件，因此用户的便利被损坏。 记录区域允许的缺陷区域的大小受限于记录区域的大小。

    摘要： A simultaneous recording and reproduction method for recording a first real time data in an information recording medium while reproducing a second real time data recorded in the information recording medium, including the steps of: searching for unallocated areas on the information recording medium and allocating at least one unallocated area, each having a size which is greater than or equal to a minimum size Y, as an area in which the first real time data is to be recorded: selecting at least one area in which each area includes a non-used area having a size which is less than or equal to K from among the allocated at least one area, wherein K denotes the size of non-used area which is allowed within a window having the same size as the minimum size Y: recording the first real time data in the selected at least one area; and reading the second real time data from at least one area in which the second real time data has been recorded, whereby each of the at least one area has a size which is greater than equal to the minimum size Y, wherein the minimum size Y is determined to enable the simultaneous recording and reproduction, even if the non-used area having a size of K exists in each of two adjacent areas where data is to be recorded during the recording operations immediately before and immediately after an access operation, or even if the non-used area having a size of K exists in each of two adjacent areas where data is to be read during the reproduction operations immediately before and immediately after an access operation.
