Patent ID: 8693143

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, the suspension being configured to be supported by a drive arm that conducts positioning of the magnetic head slider above the magnetic recording medium, 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 pair of arm parts that links the main body part and the support part, the recording signal transmission line is supported along a first route by (i) the main body part, (ii) a separate support part that connects the main body part and the support part for the magnetic head slider and that extends between the main body part and the support part separately from the pair of the arm parts of the flexure, and (iii) the support part, the microwave signal transmission line is supported along a separate route different from the first route by (i) the main body part, (ii) at least one of the pair of arm parts and (iii) the support part for the magnetic head slider, the separate support part extends parallel to and is spaced apart from the pair of the arm parts of the flexure, and a portion of the one of the arm parts that supports the microwave signal transmission line has a lamination structure in which an insulating layer that supports the microwave signal transmission line on one surface and a substrate whose portion opposing the other surface of the insulating layer has conductivity are laminated.
