Storage capacity of magnetic disk depends on

  • Tracks per inch of surface
  • Bits per inch of tracks
  • Disk pack in disk surface
  • All of above
...
Magnetic fields are used to store data on the disk surface. Data is encoded on the disk surface by having variations in the field of magnets. So storage capacity of a magnetic disk depends on

    1. Tracks per inch of surface
    2. Bits per inch of tracks
    3. Disk pack in disk surface

Can we erase data on a magnetic disk?
