    • There are provided a head gimbal assembly and an information recording and reproducing apparatus capable of easily positioning a light guiding portion and a slider on a tongue portion and performing a stable recording and reproducing operation. A head gimbal assembly recording information on a recording medium using a near-field light includes: a suspension that extends along a surface of the recording medium so as to be deflectable in a thickness direction; a support portion that is provided at a tip end side of the suspension so as to be more deflectable in the thickness direction than the suspension; a light guiding portion that has a support-facing portion provided to the support portion so as to face the support portion and introduces a light flux used for generating the near-field light; and a 3-dimensional structure that is provided to the support portion and used for positioning the support-facing portion on a desired portion of the support portion, wherein the support-facing portion has a portion in which a width of a sectional surface thereof perpendicular in a longitudinal direction of the suspension is larger than a width of a contact surface that makes contact with the support portion.
    • 提供了一种头部万向架组件和信息记录和再现装置,其能够容易地将导光部分和滑块定位在舌部上并执行稳定的记录和再现操作。 使用近场光在记录介质上记录信息的头万向架组件包括:沿着记录介质的表面延伸以沿厚度方向偏转的悬架; 支撑部,其设置在所述悬架的前端侧,以便在所述厚度方向上比所述悬架更可偏转; 导光部,其具有设置在所述支撑部上以与所述支撑部相对的支撑面对部,并且引入用于产生所述近场光的光束; 以及三维结构,其被设置到所述支撑部分并用于将所述支撑面向部分定位在所述支撑部分的期望部分上,其中所述支撑面向部分具有其截面的宽度垂直于所述支撑部分的部分 在悬架的纵向方向上大于与支撑部接触的接触表面的宽度。
