The Storage Capacity of a Magnetic Disk depends on the bits located per unit area of the disk surface. Information is stored on a disc using magnetic fields, which use different variations in the field of magnets to encode it in different locations. A magnetic field can store data and act as a secondary memory, but it cannot be continuously inserted or removed like a pen drive.

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 programs 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.
- A magnetic disk can only store values in 0 or 1, which is the binary language.
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 Storage Capacity. 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.
