  • Apparatus for improving the continuous supply or display time of full-motion video and other data
    Patent number: 5745639
    Abstract: A magnetic disk drive used for full-motion video has independently actuated read and write heads combined with a register and buffer to permit data on a disk of the disk drive to be read by the read head while simultaneously new data is being written elsewhere on a disk of the disk drive over data already read by the read head. The register and buffer ensure that new data is not written over stored data until the stored data has been read by the read head.
