<p>A track-pairing technique for use in recording and retrieving video data is described. By alternating between a pair of tracks when recording and retrieving data segments of a data stream, a video server (12) or recording disk (24) is able to take advantage of zone bit recording when recording, yet data transfer rate upon retrieval is independent of track location. As a result, guaranteed throughput is substantially improved and the number of data streams which can be simultaneously sourced increases. The inventive track-pairing technique can be embodied in a video server, a recording disk, a data layout method, or a data retrieval method. <IMAGE></p> |
