Abstract

　光学素子（３６）はヘッドスライダ（２３）の支持面（２３ａ）およびヘッドサスペンション（２２）の間に挟み込まれる。光学素子（３６）には集光面（７２）および反射面（７３）が区画される。集光面（７２）で集光される光は反射面（７３）で反射する。こうして光はヘッドスライダ（２３）の光導波路（７１）に導かれる。こうしたヘッドサスペンションアセンブリ（２１）の製造にあたってヘッドスライダ（２３）の光導波路（７１）および光学素子（３６）の相対位置が調整される。ヘッドスライダ（２３）および光学素子（３６）はこれまで以上に容易に位置決めされる。ヘッドサスペンションアセンブリ（２１）の組み立ては容易に実施される。
