Abstract: THIS REPORT will discuss a double density Floppy Disk Controller (FDC) LSI device using a micro/nanoprogramming structure' to achieve the data processing capability required for double density floppy disk control.of controlling floppy disks and data formatting, the FDC should serve as an independent processor-type device to take over most of these heavy burdens.On the other hand, the data processing speed of an FDC required for double density recording is as fast as 2ps/b, twice that of conventional single de…
