Abstract
Audio or video information is stored as data files in clusters or blocks of sectors on a magnetic disc. The data files are transferred from the disc drive to one or more buffers for respective data streaming applications. Optimal buffer size is calculated using operational parameters such as transfer rates and rotational latencies. The sectors are grouped in blocks having a size equivalent to, or slightly larger than, the size of an associated host buffer for the respective application to avoid fragmentation of the data used in each buffer fill, and thereby minimize the time required to fill the buffer from the disc drive.
