In this paper, we base on region-based disk layout and propose a data placement technique and it associated disk scheduling policy for providing periodical video broadcast services. We present a quantitative study and design algorithms, while still maintains the quality of service, for (1) placing video data on disk, and (2) simultaneously serving of maximum number of broadcast channels with minimal data buffer. We also develop a model that relates disk device characteristics to maximizing the disk utilization.
