Abstract
A magnetic head includes a microwave-generating element connected to a ground line. The ground line is made shorter by connecting the ground line to a conductive slider substrate so that the microwave-generating element is in a nearly short-circuited end condition. This allows a microwave excitation current to be efficiently supplied to the microwave-generating element, thus enabling effective microwave-assisted recording.
