Abstract
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.
