Abstract
A multimedia object is declustered across a multiple of disk drives to employ the aggregate bandwidth of the several disk drives so that continuous retrieval or display of the object is achieved. The clusters are logically defined across a plurality of disk drives instead of being physically defined so that two consecutive subobjects comprising the data object may be on the same disks. The subobjects are assigned to the disks so that the first fragment of one subobject is k disks apart from the drive that contains the first fragment of the preceding subobject, where k is a fixed stride.
