    • In a data recording and reproducing apparatus which records and reproduces a record medium in which at least two kinds of data having different data types can be recorded, data is read out from the record medium, and a digital watermark is detected from the data read out. The kind of data is determined depending upon whether the digital watermark is detected, and it is determined whether retry processing at the time of reading-out the data and verifying processing at the time of writing should be executed. The retry processing or the verifying processing is executed only for the data which is determined that the retry processing or the verifying processing should be executed. Therefore, in the case of data whose reading-out continuity is more important than reliability, the retry processing is omitted, so that time required for reading-out processing can be shortened. In the case of data whose recording continuity is more important than reliability, the verifying processing is omitted, so that time required for writing processing can be shortened.
    • 在记录和再现其中可以记录具有不同数据类型的至少两种数据的记录介质的数据记录和再现装置中,从记录介质读出数据,并从读出的数据中检测出数字水印 。 数据的种类根据是否检测到数字水印来确定,并且确定是否应当执行读取数据时的重试处理和写入时的验证处理。 对于确定应该执行重试处理或验证处理的数据,执行重试处理或验证处理。 因此,在读出连续性比可靠性更重要的数据的情况下,省略重试处理,可以缩短读出处理所需的时间。 在其记录连续性比可靠性更重要的数据的情况下,省略了验证处理,从而可以缩短写入处理所需的时间。
