Abstract
A suspension is configured to support a magnetic head slider having a recording head element for recording to a magnetic recording medium and a microwave generating element that applies a high-frequency magnetic field to the magnetic recording medium when recording is conducted by the recording head element. The suspension has a flexure that supports the magnetic head slider, a microwave signal transmission line and a recording signal transmission line. The microwave signal transmission line is connected to the microwave generating element and configured to transmit microwave signals for generating the high-frequency magnetic field. The microwave signal transmission line and the recording signal transmission line are supported between the main body part and the support part, a portion of which has a first lamination structure where a first ground layer is conductive and a first insulating layer supports the microwave signal transmission.
