Patent ID: 8587903

Claim:
A suspension that 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 to the magnetic recording medium is conducted by the recording head element, comprising: a flexure that supports the magnetic head slider; and a microwave signal transmission line and a recording signal transmission line that are supported by the flexure, the microwave signal transmission line being connected to the microwave generating element and configured to transmit microwave signals for generating the high-frequency magnetic field, the recording signal transmission line being connected to the recording head element and configured to transmit recording signals, wherein the flexure has a main body part, a support part for the magnetic head slider, and a linkage part that links the main body part and the support part, the microwave signal transmission line and the recording signal transmission line are supported between the main body part and the support part by a separate support part separated from the flexure, and a portion of the separate support part that supports the microwave signal transmission line has a first lamination structure in which a first ground layer that is conductive and a first insulating layer that supports the microwave signal transmission laminated, wherein a portion of the main body part of the flexure that supports the microwave signal transmission line has a second lamination structure in which a flexure main plate, a second ground layer that is conductive and has higher conductivity than that of the flexure main plate, and a second insulating layer that supports the microwave signal transmission line are laminated in this order, and the second lamination structure is continuously provided along the microwave signal transmission line on an entirety of the portion of the main body part of the flexure where the microwave signal transmission line is supported.
