How Does A FLOPPY DISK Work

A floppy disk, also known as a diskette, is a magnetic storage device that was widely used for data storage and transfer in the late 20th century. Here's a general overview of how a floppy disk works:

Physical Structure:
A floppy disk is a thin, flexible plastic disk usually enclosed in a protective casing. The most common size is 3.5 inches, although larger 5.25-inch floppy disks were also used in the past. The diskette is coated with a thin layer of magnetic material (usually iron oxide) on both sides.

Magnetic Coating:
The magnetic coating on the surface of the floppy disk is where data is stored. This coating is capable of being magnetized in different directions, allowing it to represent binary data (0s and 1s).

Read/Write Heads:
The floppy disk drive contains read/write heads, which are electromagnetic components that read and write data to the magnetic surface of the floppy disk. These heads are mounted on a mechanism that allows them to move across the surface of the disk.

Tracks and Sectors:
The surface of the floppy disk is divided into concentric circles called tracks. Each track is further divided into sectors, creating a grid-like structure for organizing and locating data on the disk.

Formatting:
Before using a floppy disk, it needs to be formatted. Formatting involves creating the necessary data structures on the disk to organize and track the stored information. The formatting process also prepares the disk for storing data.

Writing Data:
When data is written to the floppy disk, the read/write heads generate a magnetic field that aligns the magnetic particles on the disk's surface. The orientation of these particles represents the binary data being written to the disk.

Reading Data:
To read data from the floppy disk, the read/write heads detect the changes in the magnetic field as they pass over the surface. These changes correspond to the encoded binary data, which is then translated back into usable information by the computer.

File Systems:
Floppy disks are formatted with a file system that organizes data into files and directories. Common file systems for floppy disks include FAT12 and FAT16. These file systems provide a structure that allows the operating system to locate and manage the stored data.

Capacity and Limitations:
Floppy disks have limited storage capacity, with the 3.5-inch disks commonly having a capacity of 1.44 megabytes (MB). Larger 5.25-inch disks had lower capacities. This limited storage capacity, vulnerability to physical damage, and slower data transfer speeds contributed to the eventual decline of floppy disks as a primary storage medium.

Obsolescence:
Advances in technology led to the obsolescence of floppy disks. Modern computers and devices no longer include floppy disk drives, and higher-capacity and more durable storage solutions, such as USB drives and cloud storage, have become the standard.

While floppy disks were once a ubiquitous means of storing and transporting data, their use has become obsolete due to technological advancements and the development of more reliable and higher-capacity storage devices.
