How sensitive you ask? The gap of the head and magnetic media (explained later) is 2/1,000,000 of an inch between one another. Thats twice the length of a smoke particle. -[Logic Board Function]- The logic board is used to communicate from the BIOS and operating system. The Logic Board translates the commands into voltage fluctuations that force the head actuator to move the ganged read/write heads acrossed the platters surface. -[Spindle Function]- The Spindle's function is to spin as many as eight magnetically coated platters at several revolutions per minute, Spindle is one of the components that determine the speed of the hard drive. -[The Head Actuator Function]- The head actuator function is to move the read/write heads acrossed the surface of the hard drive. It also aligns the heads with the tracks that lie in concentric circles on the surface of the platters. -[Read/Write Heads Function]- Read/write heads attached to the ends of the moving arms, slide in unison accross both the top and bottom surfaces of the hard drive's spinning platters. The head writes data coming from the disk controller by aligning megnetic fields of particles on the platters' surface. The Read Head operates by detecting the polarities of particles that have already been aligned.
