who invented the floppy disk

The floppy disk was invented in 1971 by a team of IBM engineers led by Alan Shugart, building on a development project started in 1967 under David L. Noble at IBM’s San Jose lab.

Quick Scoop: Who invented the floppy disk?

If you’re wondering who invented the floppy disk , the credit goes to IBM—specifically a small engineering team, not a lone genius in a garage.

In 1967, IBM product manager Alan Shugart kicked off an internal project (code‑named “Minnow”) and asked a team led by engineer David L. Noble to find a cheaper, simpler way to load code into big IBM mainframes.

Their solution became the first flexible magnetic storage disk: an 8‑inch “memory disk” that IBM commercially introduced in 1971, soon nicknamed the “floppy disk” because the plastic disk inside was literally flexible.

In short: A team of IBM engineers invented the floppy disk; Alan Shugart is usually named as the lead figure behind the invention.

How it came about (mini‑timeline)

  • 1967: At IBM San Jose, project “Minnow” begins to create a low‑cost, reliable way to load microcode onto the IBM 3330 mainframe system.
  • Team: Initiated by Alan Shugart (product manager) with engineering leadership from David L. Noble and colleagues in storage R&D.
  • 1971: IBM ships the first 8‑inch floppy disk drive (23FD) with removable read‑only “memory disks,” storing about 80 KB—roughly 3,000 punched cards’ worth of data.
  • 1972: IBM secures US patents for the floppy disk and its drive, cementing the design as a new industry standard.
  • Mid‑1970s: Shugart and others help push smaller 5¼‑inch floppy disks for desktop systems, spreading the technology through the growing personal computer market.

Even today, when people ask “who invented the floppy disk,” tech histories and records (including IBM’s own and Guinness World Records) consistently point to a team of IBM engineers led by Alan Shugart.

Why this still matters now

  • The floppy disk was the first widely used removable magnetic storage for software distribution and updates, especially on big IBM systems.
  • Its success paved the way for later removable media: from smaller floppies to ZIP disks, CDs, USB drives, and modern portable SSDs.
  • In 2026, the floppy is mostly a retro icon, but it lives on as the “save” symbol in software and as a nostalgic design element in games, merch, and artwork.

You’ll still see discussions pop up on forums where people argue whether Alan Shugart alone “invented” it or whether the whole IBM Minnow team and David L. Noble deserve equal billing—most serious histories emphasize it was a collaborative IBM effort with Shugart as the key lead.
