    • A device records information in blocks having logical addresses at a physical address in a track on a record carrier. The logical addresses are translated into the physical addresses in dependence of defect management information (52,53,61,64), which includes defect entries indicating locations for replacing defective physical addresses. A read-only state of the record carrier is obtainable via a no-replacement state indicated by substantially none of the defect entries being free for use. The device has a read-only unit for setting the record carrier to the read-only state by reading original replacement information indicating a writable state, storing the original replacement information (60) in a hidden area, and writing defect management information (61) that is modified to the no-replacement state. The record carrier may be re-opened by retrieving the original replacement information (60) from the hidden area.
    • 设备在具有记录载体上的轨道中的物理地址的逻辑地址的块中记录信息。 逻辑地址根据缺陷管理信息(52,53,61,64)被转换成物理地址,该缺陷管理信息包括指示用于替换有缺陷物理地址的位置的缺陷条目。 记录载体的只读状态可以通过基本上没有缺陷条目指示的无替换状态获得,该缺陷条目是免费使用的。 该装置具有只读单元,用于通过读取表示可写状态的原始替换信息,将原始替换信息(60)存储在隐藏区域中,并将缺陷管理信息(61)写入到只读状态中, 被修改为无替换状态。 可以通过从隐藏区域检索原始替换信息(60)来重新打开记录载体。
