Hard disk drives were developed as a recording medium for computer data, and are now also used to store multimedia data such as video and audio. However, this is not yet a practical medium for use in broadcasting. We are developing a video hard-disk system that will allow high-bitrate recording/playback while maintaining video signal continuity. As a step toward realizing a video hard-disk system, we have developed a hard-disk tool capable of precisely evaluating hard disk performance. It is also essential to model hard disks to efficiently develop a video hard-disk system. In this paper, we describe a method of modeling hard disks, and show how this model can be used to improve the performance of hard disk systems.
