What does The Storage Capacity of a Magnetic Disk Depend on?

Answer:

• The amount of data that can be stored on a magnetic disc in a given space, is measured in bits per square inch
•  In order to store information on a disc, magnetic fields are used and encoded in different locations by changing the magnetic field
•  Data can be stored on a magnetic disc, but it cannot be used as a pen drive to store and remove data at will
• Until a magnetic disc is burned, there is no way to make the disc usable again
