Microphotograph of a hard disk head. The size of the front face is about 0.3 mm. One functional part of the head is the round, orange structure in the middle - the lithographically defined copper coil of the write transducer. Also note the electric connections by wires bonded to gold-plated pads.

Disk read/write heads are the small parts of a disk drive, that move above the disk platter and transform the platter's magnetic field into electrical current (read the disk) or vice versa – transform electrical current into magnetic field (write the disk). The heads have gone through a number of changes over the years.
