The magnetic surface of hard platters in a hard drive is formatted into tracks and sectors which can hold a fixed number of bytes. When data needs to be recorded, the hard disk platters rotate at high speeds and passes underneath the hard drive read/write head. The magnetic head produces a magnetic field which magnetizes the corresponding region where data is supposed to be stored. During this process, the surface acquires a magnetic flux or pattern representative of the information being stored.
