Abstract
An MR thin-film magnetic head includes a lower shield layer, an upper shield layer, a MR multilayer sandwiched between the lower shield layer and the upper shield layer, the MR multilayer being electrically connected with the lower shield layer and the upper shield layer, a current flowing through the MR multilayer in a direction perpendicular to surfaces of layers, and a lead conductor having one end electrically connected to the upper shield layer and the other end connected to a terminal electrode. The lead conductor is patterned such that an area of said lead conductor located above said lower shield layer becomes small.
