3. Storage

   • Optical
     • Data is recorded by making marks in a pattern that can be read back with the aid of light, usually a beam of laser light precisely focused on a spinning optical disc.
   • Magnetic
     • Magnetic storage or magnetic recording is the storage of data on a magnetised medium. Magnetic storage uses different patterns of magnetisation in a magnetisable material to store data and is a form of non-volatile memory.
   • Solid State
     • Comes in many forms such as a floppy disk, sd card or the classic memory stick . These are one of the most effective types of storage due to their small size, durability and portability.
