<p>Method and apparatus for continuously reading data from a compact disk drive (12) to a host computer (14) in which the data is transferred to the computer's cache memory (32) so that it is available to the computer's central processor (26) for processing without interruption. A communication link is established between a processor in the disk drive (22) and a direct memory access (DMA) controller (36) in the host computer (14). With this link established, the DMA controller directs the transfer of the incoming data stream from the drive to the cache memory (32) of the host computer. Once the data is in the cache memory (32), it is moved to the application workspace of the computer's system random access memory (RAM) (34), for processing by the central processor (26). The transfer of data by the DMA controller (36) and the temporary storage of the transferred data in the cache memory (32), allows for continuous transfer of data from the compact disk drive (12), without interruption, and without the need for reseeks of the data.</p> |
