8-inch, 5¼-inch, and 3½-inch floppy disks

8-inch, 5¼-inch, and 3½-inch floppy disks

A floppy disk is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive.  The first floppy disks, developed in the late 1960s, were 8 inches (200 mm) in diameter; they became commercially available in 1971 as a component of IBM products and then were sold separately beginning in 1972 by Memorex and others. These disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation. The term “floppy disk” appeared in print as early as 1970, and although in 1973 IBM announced its first media as “Type 1 Diskette” the industry continued to use the terms “floppy disk” or “floppy”.  Through its history, the floppy disks, initially as 8-inch (200 mm) media, later produced in 5¼-inch (133 mm) and 3½-inch (90 mm) sizes.  While floppy disk drives still have some limited uses, especially with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity, such as USB flash sticks, flash storage cards, portable external hard disk drives, optical discs, and storage available through computer networks.

  1. I’ve been around computers my entire life and floppy disks were my life at one point. Now I’m a hipster who uses them as coasters. I am always astounded when I see them on sale though!

    I’ve seen floppies as big as a foot square. We used them to boot mainframes about 30 years ago.


  3. That’s funny, I remember installing software and slapping one disk after another into the drive. I think I used to read magazines while I installed stuff. I use the small ones that came out in the nineties as coasters too. They’re a little unsteady!

    I enjoy your blog, Maryann! Good luck with the challenge –

    I’m an archivist and now spend a fair share of my job trying to extract files from old floppy disks on special computers. It’s amazing how they went from being so common to being -fashioned so quickly.

    J here, stopping by from the #atozchallenge – where I am part of Arlee Bird’s A to Z Ambassador Team.
    How has the first week of the challenge been for you so far? Are you meeting your goals of posting and hopping to other blogs?
    My blog has a giveaway with bonus a to z challenges to encourage people to visit more stops.
    I remember the 5s, which were actually floppy!!! Ha ha. Cool post.


    • It is going very well. I had been in a slump blogging wise. I used to blog every day and had been down to barely blogging at all. I decided to get back in the swing with the A to Z. I am keeping up well. Actually with posting 2 daily, I did a lot in advance. I just now have some letters that I am stump but I’ll get there.
