How is data stored and retrieved on a magnetic mass storage device?
For writing, electrical current is routed through a read/write head, which generates a magnetic charge at its tip. A bit area of a magnetic recording surface is placed in close proximity to the read/write head, and a charge is induced in the surface material. The direction of current flow through the read/write head determines the stored charge's polarity.
For reading, a bit area of the recording surface is placed in close proximity to the read/write head, andthe stored charge induces current to flow through the read/writehead. A switch connected to the read/write head detects the current flow's direction to interpret it as a bit value.
