Optical Storage MediumsThe most common way of storing data in a computer is magnetic. We have hard
drives and floppy disks (soon making way to the CD-ROM), both of which can store
some amount of data. In a disk drive, a read/write head (usually a coil of
wire) passes over a spinning disk, generating an electrical ...
