Abstract
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.
