Abstract
The present invention optimizes data placement in reference to the service of cyclic re-broadcast, typical of a media server. When the media data to be re-broadcast and the cycle of the re-broadcast are known, it is possible, according to the present invention, to calculate the portions of all the media data that will be read simultaneously and place sequentially such portions of data, so that the search time of the read/write head in the data blocks of direct access devices, such as magnetic disks, magnetic disk arrays, read-and-write optical disks, and other storage devices, can be reduced. Using the inventive data placement technology, the search time of the read/write head can be significantly reduced and the efficiency of bandwidth use can be improved, without altering typical hardware devices.
