| read/write head |
|
A device that reads (senses) and writes (records) data on a magnetic disk or tape. For writing, the surface of the disk or tape is moved past the read/write head. By discharging electrical impulses at the appropriate times, bits are recorded as tiny, magnetized spots of positive or negative polarity.
For reading, the surface is moved past the read/write head, and the bits that are present induce an electrical current across the gap.
The read/write heads on today's magnetic disks are so tiny you need a microscope to see them. The heads are attached to a pair of aerodynamically designed rails, known as a "slider," that keep the head at the proper distance from the disk platter.
Typical read/write heads use a giant magnetoreresistive (GMR) head for reading and an inductive coil for writing as in this illustration. (Illustration assistance courtesy of Hitachi Global Storage Technologies.)
