The Storage Capacity of a Magnetic Disk Depends on What?

By Esha Dhawan|Updated : September 8th, 2022

The amount of data that can be stored or the storage capacity of a magnetic disk is measured in bits per square inch or bits per unit area of the disk's surface. A disk uses magnetic fields to store information and encode it in various locations with the help of variations in the field of magnets. Although a magnetic field is a data storage device and a secondary memory device, it cannot be used like a pen drive to insert or delete information continuously.

Answer:

The storage capacity of a magnetic disk is measured in bits per unit area

In other words, 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 1 or 0 values only.

Summary:

The Storage Capacity of a Magnetic Disk Depends on What?

A magnetic disk is a data storage device and a secondary memory device that uses magnetic properties to write, rewrite and access the data. The storage capacity of a magnetic disk can be measured in bits per square inch or per unit area.
