The floppy disk was created at IBM in the late 1960s by a small engineering team led by David L. Noble, under the direction of product manager Alan Shugart, and first shipped as an 8‑inch “memory disk” drive in 1971.

Quick Scoop: Who Created the Floppy Disk?

  • Short answer:
    • A team of IBM engineers invented the floppy disk, with David L. Noble leading the hands‑on development and Alan Shugart overseeing the project as IBM’s Direct Access Storage Product Manager.
* The first commercial floppy system, the 8‑inch IBM 23FD “Minnow,” shipped in 1971.

How the Floppy Disk Was Born

In 1967, IBM wanted a cheaper, easier way to load microcode into its large disk storage systems, particularly the IBM 3330 mainframe drives. Alan Shugart at IBM’s San Jose lab asked a small team led by engineer David L. Noble to find a new solution, initially exploring tape but then pivoting to a flexible magnetic disk.

That team—Donald L. Wartner, Herbert E. Thompson, Warren L. Dalziel, Jay Brent Nilson, and Ralph Flores among others—developed what became the IBM 23FD floppy disk drive system, code‑named “Minnow.” The result was an 8‑inch flexible “memory disk” holding about 80 kilobytes of data, originally read‑only and used just to load code.

Key Facts in Bullet Points

  • Company behind it: IBM, in San Jose, California.
  • Main project lead (hands‑on): David L. Noble, engineer at IBM.
  • Product manager / overall leader: Alan Shugart, IBM’s Direct Access Storage Product Manager.
  • First format:
    • 8‑inch flexible disk, read‑only, used for loading microcode.
* Capacity around 80 KB.
  • Commercial introduction: 1971, as the IBM 23FD drive and diskette.
  • Nickname “floppy”: Because the thin plastic disk inside the jacket was physically flexible.

Mini Timeline (So You Can Place It in Time)

  1. 1959 (inspiration): Telefunken used a flexible magnetic disk in its “Plattendiktiergerät Traveller,” an early hint of the idea.
  1. 1967: IBM begins formal development; Shugart assigns Noble’s team to find a new code‑loading method for mainframes.
  1. 1971: IBM ships the first 8‑inch floppy disk drive system (23FD/Minnow) as a read‑only “memory disk.”
  1. Early–mid 1970s: Read/write floppies and then smaller sizes appear; Shugart later helps introduce the 5.25‑inch format at Shugart Associates in 1976.

In forum discussions, you’ll often see people say “Alan Shugart invented the floppy” or “David Noble invented the floppy.” Both are partly right: Shugart drove and managed the program, while Noble and the Minnow team engineered the actual disk and drive hardware.

Multiple Viewpoints: Who Gets the Credit?

Because this is a classic team invention , different sources emphasize different names:

  • “Alan Shugart created the floppy disk”
    • Guinness World Records credits a team of IBM engineers led by Alan Shugart with inventing the first floppy disk in 1971.
* Biographical notes on Shugart say that the group that invented the floppy reported to him.
  • “David L. Noble invented the floppy disk”
    • Some histories name Noble directly as the inventor, noting that Shugart assigned him the job and that his engineering team delivered the IBM 23FD system.
  • “IBM engineers invented the floppy disk” (team view)
    • Technical and historical writeups emphasize the broader engineering team—Wartner, Thompson, Dalziel, Nilson, Flores—behind the Minnow project, framing it as a collective IBM development rather than a single‑person breakthrough.

A balanced way to phrase it for a modern reader is:

The floppy disk was invented at IBM around 1967–1971 by a team of engineers led by David L. Noble, working under disk‑storage manager Alan Shugart, who championed and directed the project.

Today’s Angle and “Trending” Relevance

Even though floppy disks are obsolete in daily use, they’re still a cultural icon —they live on as the “save” icon in software, retro‑tech decor, and nostalgia posts on social media. Recent design and tech‑history blogs (published in the mid‑2020s) revisit the floppy as an 80s and 90s symbol, tying it to retro aesthetics and modern throwback branding.

You’ll often see lightweight forum threads asking “who created the floppy disk?” where answers alternate between “Alan Shugart,” “David Noble,” or just “IBM.” In more detailed discussions or tech history posts, people usually clarify that it was an IBM team effort in 1967–1971, with Noble as engineering lead and Shugart as the manager and champion.

TL;DR:
If you need a simple, accurate line for a post:

The floppy disk was created at IBM by a team of engineers led by David L. Noble under project leader Alan Shugart, and first released as an 8‑inch “memory disk” in 1971.
