PROBLEM TO BE SOLVED: To obtain accurately synthesis data with simple constitution without using synchronizing control at the time of recording/reproducing when high speed digital data is divided into plural parts and they are recorded, and analysis is performed by synthesis data after reproduction in the case of analyzing high speed digital data. SOLUTION: This device is constituted so that digital data divided into plural parts are recorded in recording devices 31, 32 respectively, while time signals (synchronizing digital signal) from a time signal generator 10 are simultaneously recorded corresponding to each divided digital signal adding by multiplexing and the like. Therefore since synthesis is performed based on coincidence of collation between reproduced each synchronizing digital signal after output of reproducing divided digital data, synchronizing control in recording/ reproducing is not required, highly accurate synthesis and data analysis can be performed with simple constitution.
