PURPOSE:To prevent a rerecording and to accurately and rapidly perform a search by recording a specific signal in a signal recording area within a picture recording medium, detecting this signal and discriminating the presence or absence of a subject recording to the corresponding picture recording area. CONSTITUTION:In a storage part 2, the bit of the right end of a shift register is connected with a detection circuit DC. When any one of 5 kinds of start signals appears, an output signal showing that a picture signal is transferred to a memory cell MC1 by detecting the start signal or that the cell MC1 becomes a used one is outputted to an output terminal MC1k. All output terminals MC1k to MC20k of the detection circuit DC are connected with a display circuit DP. By the output of the circuit DP, a display device 201 displaying a memory cell in which start signals are outputted or a used memory cell is driven. In this case, a segment corresponding to the used memory cell colors by receiving the output signal of the detection circuit DC.
