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 https://hubpages.com/technology/histofstoragedevice
