A New Scheme to Evaluate Hard Disks for Video Application

Abstract

Hard disks are used as recording media for video signals Although they are designed for computer storage, there are some problems in recording video signals on hard disks. We are developing a video hard-disk system that has efficient recording/playback, while maintaining continuity for video applications. A hard disk evaluation tool for video application is indispensable for developing a video hard-disk system, because a conventional benchmark test cannot evaluate it throughly. In this paper, we describe an evaluation tool for video applications, capable of evaluating hard disk performance precisely and capable of aiding the design of the system.
