Of course none of us use floppy disks to store data anymore but they used to be one of the most useful data storage devices at one point in time. I remember storing all my essays and papers and what not while I was in high school. Good times. Although we do not use floppy disk anymore (some still do) it is important to sometimes take a walk down the memory lane and take a look at them. Here are some pointers that show the evolution of Floppy disks.
1971
- IBM introduced 8 inch floppy disk in 1971
- Initial capacity approximately 100KB
- Radioshack had an internal floppy drive which was capable of storing 5KB.
1976
- Shugart introduced 5 1/4 inch floppy disk in 1976
- Initial capacity = 100KB
- Later the capacity was upto 1.2 MB
- In 1977 Northstar became the first computer with built in 5 1/4 inch internal floppy drives.
1980
- Sony introduced 31/2 inch floppy disks in 1980
- It could hold upto 400K
- Apple Macintosh in 1984 had an internal floppy drive capable of holding 400KB
Hope you enjoyed a little “Floppy Drive” history
