  1. The evolution of the floppy disk Floppy disks shrunk over time, from the original 8-inch disk, to the 5-1/4 inch format, and eventually down to the 3-1/2 inch disk that wasn’t nearly as floppy as the original. Floppy disk drives were reduced in size as the disks themselves became smaller.

    What was the first floppy disk?
    The floppy disk drive ( FDD) was invented at IBM by Alan Shugart in 1967. The first floppy drives used an 8-inch disk (later called a " diskette " as it got smaller), which evolved into the 5.25-inch disk that was used on the first IBM Personal Computer in August 1981.

    How much memory did the first floppy disk have?
    The first 8-inch floppy disk had a storage capacity of about 80 kilobytes. By 1986, IBM introduced the 3-1/2 inch floppy disk with 1.44 megabytes of storage space. This may seem like very little now, but at the time it was hard to imagine needing more space than that. How much memory is on a old floppy disk?

    Why do floppy disks still exist?
    Therein lies the biggest reason that floppy disks are still in demand in some corners of industry. “In the 1990s, hundreds of thousands of industrial machines were built around floppy disks, which were high-tech of the time,” he tells me. “They were built to last fifty years.”

    What came before floppy disk?
    What came before floppy disk? Cassette Recorder Even floppy disk drives were rare at the time. When you turned the computer off, you’d lose your data, unless you had something to store it on. The solution that the first PC makers came up with was to use a cassette recorder. Do old floppy disks have any value?

      In 1981, Sony introduced their 3+1⁄2-inch floppy disk cartridge (90.0 mm × 94.0 mm) having a single sided unformatted capacity of 218.8 KB and a formatted capacity of 161.2 KB. A double sided version was available in 1982. This initial Sony design was similar to other less than 5+1⁄4-inch designs but somewhat simpler in construction. The first computer to use this format was Sony's SMC-70 of 1982. Other than Hewlett-Packard's HP-150 of 1983 and Sony's MSX computers …
