Floppy Disk 🖪

(Hi friends... today I 'am going to explain about the History of the floppy disk and Types of the floppy disks...So read the post and renew your knowledge about the history of FLOPPY DISK.)

Alternatively referred to as a floppy or floppy disk, a floppy diskette is a storage medium capable of holding electronic data, like a computer file. The floppy disk was created in 1967 by IBM as an alternative to buying hard drives , which were extremely expensive at the time.

Use of Floppy Disk

Early computers did not have CD-ROM drivers or USB; floppy disks were the only way to install a new program on a computer or back up your information. If the program was small(less than 1.44MB for the 3.5" floppy disk), it could be installed from one floppy disk. However, because most programs were larger than 1.44MB, diskettes were usually required. For example, the diskette version of Windows 95 came on 13 DMF diskettes and was installed one disk at a time.

Floppy disks were also a common place for users to store and backup their files. For example, a word processing file could be another computer or stored as a backup.

Are floppy disks still used today?

There are still a few diehards who are using floppy disks, and some government agencies still even use the 8" version. However, since the early 2000s , computers no longer shipped with floppy disk drives as users moved to CD-R and ZIP drivers, and later USB jump drivers as capacities rose and prices fell. All the latest versions of Microsoft Windows also no longer include support for putters do not come with them.

How dose floppy disk store data?

A floppy drive is a magnetic medium that stores and read head. When a 3.5" floppy diskette is inserted into the drive, the metal slide door is opened to expose the inner magnetic disk. The read/write head uses a magnetic polarity of 0 or 1. Reading this as binary data the computer can understand what the data is on the platter. For the computer to write information to the platter, the read/write head aligns the magnetic polarities, writing 0's and 1's that can be interpreted late by another device.

Types of Floppy Disks

8" Floppy Disk

the first floppy disk was introduced in 1971. It was 8" in diameter with a magnetic coating, enclosed in a cardboard case with the capacity of one megabyte. Conversely to hard drives, the heads touched the disk, like in a cassette or video player that wears the media down over time.

The next year, on June 6, 1972, the floppy disk was patented by Ralph Flores and Herbert Thompson. The floppy disk drive was patented the same year, on June 18, 1972, by Warren Dalziel, Jay Nilson and Donald Warner.

5.25" Floppy Disk

The 5.25" floppy disk first started development in 1976 and became a standard in 1978.These disks were originally released with only 160 KB of disk space. They were common in the 1980s and stopped being used in the early 1990s with the advent of the CD-ROM drives.

3.5" Floppy Disk

The 3.5" floppy was created by IBM in 1984 and came with a total capacity of 720 KB. The 1.44 MB floppy diskettes were used wildly in the 1990s and were seldom found or used by 2000s
