<p>An information storage control method using a disk-shaped recording medium (10, 801) includes a step of dividing first video information (A1, A2, A3,...) into a plurality of data blocks, a step of discretely storing in a disk-shaped recording medium (10, 801) the respective data blocks in a time order in a direction of continuously accessing the recording medium at such intervals that allow writing and reading operations of the video information on a real time basis only through the continuous accessing operation to the recording medium without involving the seeking operation and latency thereof, and a step of storing data blocks of second video information (B1, B2, B3,...) in between the data blocks of the first video information discretely stored. Thereby, there is provided a low-cost video information reading and writing apparatus (500) which is fast in its response and which requires a less capacity of buffer memory. <IMAGE></p> |
