Floppy disks are still in use today, in planes, trains, industrial sewing machines and more
In the late 1960s, IBM engineers Alan Shugart and David L. Noble envisioned a compact and portable solution for storing data. This pioneering work, Project Minnow, led to the creation of the first commercially viable 8-inch floppy disk in 1971. Its 79K of storage may seem like nothing to you, but it held the equivalent of 3,000 punched cards. Which would you rather drop? A single disk or thousands of cards?

Pour Some Shugart on Me
The 5 1/4 minifloppy was a huge hit for Shugart Associates. Founder Alan Shugart would go on to found the company that would eventually turn into Seagate. (1978) #retro #technology #floppy #bitstory

Floppy Disk History: The Evolution of Personal Computing
In the mid-70s I heard about floppy drives, but they were expensive, exotic equipment. I didn’t know that IBM had decided as early as 1967 that tape drives, while fine for backups, simply weren’t good enough to load software on mainframes. So it was that Alan Shugart assigned David L. Noble to lead the development of "a reliable and inexpensive system for loading microcode into IBM System/370 mainframes" using a process called Initial Control Program Load (ICPL).

History of storage devices | hubpages
Today,
people can carry several gigabytes of data in their pockets. However, pen
drives are still a relatively new medium, and their forefathers have been
around for a while. I describe in short the history of storage devices in
respect to the year they were first used.
1890: Hollerith
punch card
The punch card
is used as a
digital data
storage device for
the first
time, during the US
population
census in 1890-91.
1937: Punch tape
Computer
pioneer
Konrad Zuse
uses punch
tape to feed
his Z1 with
data. Punch
tape is used
for data
storage as late
as the 80s,
mainly in
administrative
agencies.
1969: 8-inch
floppy
The invention
of floppy disks is
a milestone in
the development
of storage
media. In 1969, an
IBM research
group lead by
Alan Shugart
introduces the
first 8-inch
floppy disk with 80
KB of storage
space.
1976: 5.25-inch floppy
The 5.25-inch
floppy has a Men Moving capacity of
720 KB and is
the only mobile storage
Option for private users, till it is replaced
by the 3.5-inch standard.
1983: SyQuest
Drive
Removable hard
disks are expensive, but
offer quicker
data transfer and relatively
larger
capacities.
SyQuest succeeds in
designing a
100 mm disk with 5 MB of
storage space.
1989: Compact Disk
Finally,
everyone can burn CDs. Blanks
are initially
very expensive, but
eventually the
price of the media will fall to
very
affordable.
1991: MO Disk
Magneto-optical
media is considerably more secure
than CDs or floppy
disks. However, these drives
and blanks are
expensive, and there is no mass
market for
them. Sony tries to establish the Minidisk
as a medium,
but fails
1994: Iomega Zip
With Zip,
Iomega brings a 100 MB medium
to the
market--real competition for the
3.5-inch
floppy disk. Poor marketing and
other failures
prevent its breakthrough.
1995: Smart Media
Toshiba
presents the Smart Media
Card as a
rival to the recently
Introduced Compact
Flash
memory card standard
by
SanDisk. By
1999, the standard for
the coming
years is more or less
settled to be
the SD card.
1996: Dov Moran
The inventor
of the USB pen
drive is first
scoffed at. But
his new NAND
Flash storage
device soon
proves to be
ideal and
finally replaces the
3.5-inch
floppy after 15 years.
1998: Adhesive Tape
While
preparing for their CeBIT
visit in 1998,
physicians Steffen
Noethe and
Matthias Gerspach
discover that
adhesive tape can be
coded with
data using lasers. Today
there is a
whole line of storage devices
based on these
clever adhesive strips.
2001: DVD-R
Recordable
discs with more than 4 GB of data
capacity are
introduced and are soon affordable
for every
computer user.
2002: Blu-ray
A blue laser
allows considerably finer data
structures on
optical media. After an intense
war of formats
years later, Blu-ray comes out
on top against
the HD-DVD and becomes the HD
video medium.
2003: Iomega
The Rev is a
2.5-inch removable hard disk system with
a capacity of 35 GB, in which the motor and
disk are
part of each
unit. Only the electronics and reading
heads are
found in the drive.
2005: U3
Applications directly
run from a USB stick without
being
installed on the host system.
2008: HAMR
A combination
of laser and magnet heads
allows
considerably higher Moving Van data densities on
hard disks and
is on the brink of going from the
lab into
production.
2009: Bacteria as biostorage (future)
The bacterium
Deinococcus radiodurans is one possible
Future storage
medium: data sequences can be coded
and implanted into
the bacterium. The data will be safe
even after
hundreds of generations--and will have been
duplicated
billions of times
