PROBLEM TO BE SOLVED: To provide a simultaneous recording/reproduction controller for a recorder capable of ensuring the writing execution of information even when simultaneously performing the writing and reading of information when the reading request is issued during the writing of the information. SOLUTION: This simultaneous recording/reproduction controller 1 integrated into a monitor device inputs video data from a camera 2, and writes (records) the video data in recorders A and B, and supplies (reproduces) the input video data or the video data read from the recorders A and B to a monitor 3. When a reading request to one recorder is issued during the writing processing in the recorder, the simultaneous recording/reproduction controller 1 changes the object of the writing processing to the other recorder, and carries out the writing processing to the other recorder, and carries out the reading processing to one recorder.
