Describe the parts of a magnetic hard disk.

What will be an ideal response?

A magnetic hard drive has one, two, or more platters, or disks, that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bottom of each disk have a read/write head that moves across the disk surface as all the disks rotate on a spindle. The read/write heads are controlled by an actuator, which moves the read/write heads across the disk surfaces in unison. The disk surfaces are covered with a magnetic medium that can hold data as magnetized spots.
