Hardisk store information with the help of disk which are continually spinning. these rotating disk are coated with magnetic material and stacked(heap) with space between them. Rotating disk having cocentric circles made by magnetized surface known as tracks . Each track divided into small parts called sectors.
A magenetic head is present on both sides of every disk which are using for read/write the information.magentic head float over the disk with the help of electricity and magenetism when disk start moving. A question arise in every person mind when head float why the disk not damage.the main reason is head only float over th disk and a very small distance is lying between two head that is 300times smaller than a human air. finally data are written in the form of 0 and 1.
