     • storse a lot of data
   • agsample
     • floppy disks,
     • crdit cards
     • magnetic recording tape
     • magnetic strips

3. solid state storage

   • egsamples
     • flash memory'
     • memry card
     • memry sticks
   • dissadvanteges

4. about it

   • Optical storage is the storage of data on an optically readable medium. 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.
