If a flash detector determines that a video signal generated by an imager is affected by a flash when an electronic shutter is used, the imager generates the video signal representing a preceding unit image determined to be affected by the flash, and then a video signal representing a succeeding unit image that is consecutively exposed from the previous unit image for the same exposure period as the preceding exposure period, by setting a next time of a read signal to be earlier than a preceding time. A flash corrector uses the video signal representing the preceding unit image determined to be affected by the flash, and the video signal representing the succeeding unit image following the preceding unit image to generate a video signal in which a bright portion having a band shape affected by the flash is corrected.

In order to perform simultaneous recording of a plurality of pieces of real time data, a large capacity of buffer memories were required. In addition, it was difficult to reproduce data which was recorded by a different apparatus. The present invention has an objective of providing an information recording medium, a simultaneous recording method, and an information recording and reproduction apparatus which guarantee simultaneous recording. The simultaneous recording is guaranteed by reproducing data in each of areas having at least a minimum size fulfilling the simultaneous recording condition which allows for the number of access operations which is twice the number of pieces of real time data to be recorded, and when the data amount in the buffer is empty, switching the current recording operation to another recording operation to continue recording.
