Abstract: Apertures are formed in the portion of a flexure adjacent to the soldered portions between the bonding pads of the slider and the lead pads of lead end portions. With this, an adhesive agent for bonding the slider to a flexure tongue is moved downward from the apertures so there is no fear that the adhesive agent will contact the lead pads and the bonding pads. This design prevents the protrusion of an adhesive agent from short-circuiting the flexure, and absorbs a warp produced by shrinkage of a soldered portion by decreasing rigidity of the flexure. When both the bonding pad formed on the slider and the lead pad of a lead fixed to the platform of the flexure are disposed and soldered, the quality of the soldered portion is improved by locating the pads as close to each other as possible.

Abstract: A magnetic head device which can accommodate higher data transfer rates can be implemented by using lead wires. A magnetic head device 1 according to the present invention includes a head slider 3 having a magnetic head 2 having a data reading element and a data writing element, a reading lead RL for transferring data between the data reading element and external devices, the reading lead configured by a pair of lead wires which are twisted together, and a writing lead WL for transferring data between the data writing element and external devices, the writing lead configured by a pair of lead wires which are untwisted but arranged in parallel to each other. Thus, the magnetic head device can accommodate higher data transfer rates by using the writing lead WL configured by a pair of lead wires which are untwisted but arranged in parallel to each other.

Abstract: In order to provide a suspension, a head suspension assembly, and a disk drive apparatus that can contribute to an increase of record and playback reliability, holes 3 c in ribs 3 b of the head suspension assembly 3 are provided. This design decreases the displacement of a head slider 2 that is caused by Karman vortex streets occurring near the ribs 3 b in company with the rotation of the magnetic disk 1.
