The first floppy disk when was it invented

The disks were 8 inches in diameter and had a capacity of K, I think. Since they were so large! We used floppy disks and cassettes mostly as paper tape replacements, but we also appreciated and exploited the random access nature of disks. Our operating system had a set of logical devices source input, listing output, error output, binary output, etc. The rest of the operating system was basically a command monitor. The commands had mainly to do with file manipulation.

The entire operating system and all of the application programs were in HP series assembly language. Subscribe to the Inventors Newsletter. Sponsored Links. Call Toll-Free. The nickname "floppy" came from the disk's flexibility. A floppy is a circle of magnetic material similar to other kinds of recording tape such as cassette tape , where one or two sides of the disk are used for recording.

The disk drive grabs the floppy by its center and spins it like a record inside its housing. The floppy disk was considered a revolutionary device in the " history of computers " due to its portability, which provided a new and easy physical means of transporting data from computer to computer.

So, in effect, the first floppies were used to fill another type of data storage device. Additional uses for the floppy were later discovered, making it the hot new program and file storage medium. Wang wanted a smaller floppy disk and drive to use with their desktop computers. These floppies were encased in hard plastic, but the name stayed the same. They stored kb of data, and later K double-density and 1.

The following interview was done with Richard Mateosian, who developed a floppy disk operating system for the first "floppies. The disks were 8 inches in diameter and had a capacity of K. Since they were so large, we divided them into four partitions, each of which we regarded as a separate hardware device -- analogous to a cassette drive our other main peripheral storage device.

We used floppy disks and cassettes mostly as paper tape replacements, but we also appreciated and exploited the random access nature of disks. Our operating system had a set of logical devices source input, listing output, error output, binary output, etc. The rest of the operating system was basically a command monitor.
