Storage Capacity of a Magnetic Disk
A flat disc with a magnetic coating that can store data is known as a magnetic disk. This is a type of secondary memory and various programmes and files are kept on it.
A magnetic disk uses a magnetization process to write, rewrite as well as access the data. Moreover, a magnetic disk cannot be made reusable again until it is burned. The magnetic material on both sides of the disk can only store data in binary language or 1 or 0 values.
Magnetic discs are circular, flat pieces of metal or plastic that have an iron oxide coating on both sides. A recording head records input signals—which could be audio, video, or data—as magnetic patterns or spots in spiral tracks on a disk's surface as the disc is rotated by a drive unit.
Summary:
The Storage Capacity of a Magnetic Disk Depends on What?
The number of bits positioned per square inch of a magnetic disk's surface determines how much data can be stored on it. Magnetic fields, which use multiple variations in the field of magnets to encode information in various locations, are used to store information on a disc. A magnetic disk can only store values in 0 or 1, which is the binary language.
