摘要： A magnetic head suspension includes a flexure portion, a load bend portion, a load beam portion, and a base portion. The load beam portion includes: a base end area continuously connected with the load bend portion; an intermediate area extending from the base end area toward a tip end side, and a tip end area extending from the intermediate area toward the tip end side to reach the magnetic head mount area. The base end area has first side edges tilted so as to gradually approach a central longitudinal axis line of the magnetic head suspension as the first side edges go toward the tip end side. The intermediate area has second side edges continuously connected with the first side edges and configured to be substantially parallel with the central longitudinal axis line or to be tilted to gradually approach the central longitudinal axis line as the second side edges go toward the tip end side.

摘要： The present invention provides an improved magnetic head suspension including a flexure with a flexure wiring structure therein, a load beam constituting a suspension in cooperation with the flexure, and a relay FPC with a flexure wiring structure therein for connection between the flexure and an external wiring structure. A flexure signal line portion has a characteristic impedance matching with that of an FPC signal line portion. A connection portion of the flexure wiring structure has a width substantially equal to that of the FPC signal line portion, and has a length determined by multiplying a positional error in joining between the flexure and the FPC by two and adding the result to the width of the connection portion of the FPC wiring structure. The connection portion of the FPC wiring structure has a width substantially equal to that of the flexure wiring structure, and has a length determined by multiplying the positional error by two and adding the result to the width of the connection portion of the flexure wiring structure. The connection portion of the flexure wiring structure crosses the connection portion of the FPC wiring structure at right angle and is connected thereto.

To a distal end section of a supporting part that is positioned on a distal side of the open section, first and second-distal side-metal plates are fixed so as to be positioned on an outer side of the distal end side-center-support plate forming region in a width direction, and to a proximal end section of the supporting part that is positioned on a proximal side of the open section, first and second-proximal side-metal plates are fixed so as to be positioned on an outer side of the proximal end side-center-support plate forming region in the width direction. The first and second-distal side-metal plates form a distal end side-support plate in cooperation with the distal end side-center-support plate forming region.
