  Abstract

Many popularly used recent high-speed and high-capacity disks use the Zone structure in which a disk consists of multiple zones. A zone-structured disk has multiple zones, and the bandwidth and the number of sectors in each zone art different from each other. When the previous studies that modeled disks based on the assumption that the number of sectors in all tracks are same are applied to the zone-structured disk and the video data stored in a round-robin manner are read out with the SCAN technique, the transfer rate of the disk is fixed with that of the innermost zone. And excessive disk space is wasted either. To resolve the problem, this paper proposes a method for reconstructing the physical zones into logical zones by spilt and merge operations and develops a method for determining optimum transfer block size.
