The GMR head is made up of alternate nano layers of copper and iron. These ‘layers' are 50,000 times smaller that the width of a hair on your head! This is said to the first real application of nanotechnology.
Hitachi is trying to produce a GMR head that can read even smaller packets of magnetic data. This can be done by increasing the signals gained from the magnetic packets of data.
It is predicted that, in the near future, data storage on notebook and desk-top computers will rise to at least one terabyte which is over one thousand gigabytes.
