For reading, the surface is moved past the read/write head, and the bits that are present induce an electrical current across the gap. See hard disk. THIS DEFINITION IS FOR PERSONAL USE ONLY.

The data are rendered unreadable, and the drive has to be replaced. However, in some cases, the data can be recovered (see data recovery). The read/write head on a hard disk hovers above the ...
