Hard Disk Drive Hard Disks are coated whit a thin magnetic layer, usually of iron oxide.
Cylinders : concentric circles starting at the outside and end on the inside. Tracks : These are the lines of the disk. Sectors : Each track on the disk is divided in sectors.
Cluster :  Is the length of the track taken as a processing unit in each read or write to the disk, which is equivalent to the length of a sector on floppy disks or set of 4 or 8 contiguous sectors on disk hard. To write, head is positioned over the cell to record and passed through it a current pulse, which creates a magnetic field on the surface. When reading data from disk is passed over the area that is required and will detect a magnetic field as found magnetized in one direction or another, indicate whether the position is stored in a 0 or a 1.  In writing case is reversed, the head is a current which causes a magnetic field and depending of the sense of this place a 0 or 1.
