Overview
A hard drive reads and records information off of stacked disks called platters. The way information is stored is a magnetic charge is either put in or read from the metal disks. This allows them to stay constant even when a computer is off. The size of the hard drive depends on the amount of particles measured in bits per square inch that can be magnitized. Hitachi has been thoroughly investigating the advantages of perpendicular magnetic recording (PMR) since 2006. It has allowed them to raise the areal density in each of their platter
