Yoshiro Nakamatsu
Among Nakamatsu's early inventions is the Shoyu Churu Churu, a siphon pump used in the home to move soy sauce from large containers to smaller vessels for cooking and serving. His patented inventions include:
Based upon a patent issued in 1952, Nakamatsu claims to have invented the first floppy disk well before IBM's floppy disk patent was filed in 1969. However, what Nakamatsu patented in 1952 was a paper for optical sound player. In contrast to a floppy disk, this Nakamatsu patent discloses the use of printed paper for storage instead of the magnetic material of a floppy disk. It is not rewritable and lacks most elements of the IBM floppy disk patent. Since the paper was 'floppy' material, he claims he had invented the floppy disk (sometimes he uses the phrase "floppy media"); however, it should be noted that flexible magnetic recording media was well known prior to 1952, in tape and wire recording.
M-Systems
M-Systems Ltd., (sometimes spelled msystems) was a Nasdaq-listed Israeli producer of flash memory storage products founded in 1989 by Dov Moran and based in Kfar Saba, Israel. They were best known for developing and patenting the first flash drive, marketed in 1995 as "DiskOnChip", and the first USB flash drive, marketed in 2000 as "DiskOnKey". They also created the patented True Flash Filing System (TrueFFS) which presented the flash memory as a disk drive to the computer. After 17 years of business, they were acquired by their prior competitor, SanDisk, in 2006.
The DiskOnChip (DOC) was developed at the R&D Center established by M-Systems called EUROM. Rick Iorillo, Rony Levy and David Deitcher were the individuals that worked on the development and marketing of the first 2 MB DOC. This product went on to receive the Most Innovative Award from EDN in 1995 and later went on to become the Flash Drive and DiskOnKey.
