    • PURPOSE: A defect management method of a write-once optical recording medium is provided to replace a defect area, and to record defect management information by using plural TDMAs(Temporary Defect Management Areas) to use the TDMAs, thereby obtaining sufficient TDMAs. CONSTITUTION: Management information is recorded in the first TDMA having a fixed size. When the recording in the first TDMA is completed, management information is recorded in the second TDMA assigned in a specific zone within a spare zone. The first TDMA is assigned to a lead-in zone. The second TDMA is assigned every spare zone which is variably assigned. The second TDMA is used in opposite direction to the spare zone for replacing a defect area.
    • 目的:提供一次写入光记录介质的缺陷管理方法来代替缺陷区域,并通过使用多个TDMA(临时缺陷管理区域)来记录缺陷管理信息以使用TDMA,从而获得足够的TDMA。 构成:管理信息被记录在具有固定大小的第一TDMA中。 当第一TDMA中的记录完成时,管理信息被记录在在备用区内的特定区域中分配的第二TDMA中。 第一个TDMA被分配到导入区。 每个可变分配的备用区分配第二个TDMA。 第二TDMA用于与备用区相反的方向,用于替换缺陷区。
