ABSTRACT:
The objective of this invention is to provide a type of data processing device and a type of data recording/reproduction device that can restart data write processing correctly from an interruption position after data write processing on a recording medium is interrupted. When write is interrupted, prescribed information that indicates the tail of the data written before said interruption is obtained from the written data. When write is restarted, first, data read processing is started. From the read data, the tail of the write data before said interruption is determined based on said obtained information. Then, data write processing is restarted and connected to said determined tail of the write data. In write clock signal generating part (45), write clock signal CK3locked to the phase of read clock signal CK2is generated. Consequently, it is possible to suppress discontinuity in the connection of write in company with switching from read processing to write processing.
