    • In order to realize efficient access in the case of restoring read failure data by RMW at the time of data rewriting, a recording apparatus includes a write/read unit capable of performing data writing in a second data unit, in which a plurality of first data units of a predetermined amount of data are consecutive, and data reading in the first data unit with respect to a recording medium and a control unit. In response to a rewrite instruction of data, the control unit instructs the write/read unit to generate write data in the second data unit using update data relevant to the rewrite instruction and recorded data read out from the recording medium and to write the write data at a non-recording address on the recording medium, and generates or updates replacement information for associating an address at which the write data is written, as a replacement destination, with an address of a replacement source. In addition, the control unit generates extended replacement information including validity/invalidity information for each piece of data in the first data unit in the write data, as information linked to the replacement information, according to predetermined conditions.
    • 为了在数据重写时通过RMW恢复读取失败数据的情况下实现高效访问,记录装置包括能够在第二数据单元中执行数据写入的写入/读取单元,其中多个第一数据 预定量的数据的单元是连续的,并且在第一数据单元中相对于记录介质和控制单元的数据读取。 响应于数据的重写指令,控制单元使用与重写指令相关的更新数据和从记录介质读出的记录数据指示写入/读取单元在第二数据单元中生成写入数据,并写入写入数据 在记录介质上的非记录地址处生成或更新用于将写入写入数据的地址作为替换目的地与替换源的地址相关联的替换信息。 另外,控制单元根据预定条件,生成包括写入数据中的第一数据单元中的每个数据的有效/无效信息的扩展替换信息作为链接到替换信息的信息。
