An improved transverse pressurization contour (TPC) slider and method for manufacturing the same in which the TPC surfaces occupy more than 50% of the slider rail surfaces. The rail widths may be defined by a shallow etching step in conjunction with a deeper central saw cut defining an ambient pressure slot. Alternatively, the rail widths may be defined by multiple saw cuts. The air bearing surfaces (ABS) may be defined in a single photolithographic step. Utilizing TPC surfaces of greater than 50% of the rail surfaces allows the use of saw cuts to define the rail dimensions and ambient pressure slot with decreased sensitivity to lateral mispositioning of the cuts. The improved TPC slider and method for manufacturing the same provides a simplified, reproducible device and process which is much more rapidly effectuated than processes relying on conventional chemical etching, reactive ion etching or ion milling operations. Also in accordance with a process of the present invention, leading edge ramps of the rails may be advantageously formed prior to definition of the air bearing surfaces and transverse pressurization contours.

A low-impedance biological electrode device for establishing electrical connection between the human body and electrical recording or stimulating apparatus without the use of conducting fluids, such as, gels, pastes and electrolytes, comprising, a substantially planar relatively thin electrode body, having as the electrically conducting connecting unit contacting the human body, a plurality of individual longitudinally extending strands, fibers, or filaments of conducting material embedded in a pressure-sensitive or solvent-activated adhesive which serves to bond the strands together in a composite connecting unit and to bond the connecting unit on one side to said electrode body and on the other side or interface to the human body, a modification being the use of strands cross-oriented with respect to the longitudinal strands, as exemplified by woven conductive material, the connecting unit being provided with a transverse bus bar in the form of metal foil in electrical contact with an electrical connecting element for conducting current from the connecting unit in contact with the human body to the electrical recording or stimulating apparatus.

A disk drive head-gimbal assembly () is disclosed, which includes what may be characterized as a flexure () with an integrated trailing edge limiter. The head-gimbal assembly () includes a deflectable flexure tongue () and a bond pad platform () that is spaced from this flexure tongue (). At least one bridge () extends between and structurally interconnects the flexure tongue () and bond pad platform (). A slider assembly (), including a slider positioner () and a slider (), is mounted on the flexure tongue (). The bond pad platform () is used to establish an electrical connection with the slider ().

A head gimbal assembly includes a slider assembly and a flexure tongue that cantilevers in a first direction and supports the slider assembly. The slider assembly cantilevers away from the flexure tongue in a second direction different than the first direction. A load beam imparts a force on the flexure tongue and generates a first net torque on the slider assembly. The cantilevering of the slider assembly decreases a magnitude of the first net torque on the slider assembly. The force on the flexure tongue can also generate a second net torque on the slider assembly that is oriented about a second axis different than the first axis. The slider assembly can cantilever in the second direction to decrease the magnitude of the second net torque on the slider assembly. Portions of the flexure tongue and the slider assembly can be spaced apart from one another to form a gap that is directly between the flexure tongue and the slider assembly. The flexure tongue can includes a tongue aperture and/or one or more notches that increase the deflection of the flexure tongue to decrease the first net torque.

An attachment of multiple head arm assemblies to an actuator in a magnetic data disk drive system. A leaf spring applies a uniform load against angle surfaces formed on the head arm assemblies. This creates forces on the head arm assemblies to align reference surfaces formed on the head arm assemblies against reference surfaces formed on the carriage. Loads on the head arm assemblies are due to the geometry of the parts rather than on screw torques.

Apparatuses and a method are provided to prevent buckling damage to a disk drive flexure when the read/write heads are subjected to high stiction loads and when backward rotation of the disks occur. Excessive flexure displacements due to the buckling loads are prevented by transferring some of the force of the buckling load to the stronger, stiffer load beam. Buckling limiter features are provided on either the load beam or flexure, or on both the load beam and flexure wherein the force of the buckling load causes contact of a component on the flexure against a component on the load beam. The contact between the components causes some of the buckling load to be transferred to the load beam. Each of the preferred embodiments provide different structural components forming the buckling limiting features.

An improved slider with controlled fly height and decreased sensitivity to externally applied roll moments. In a two rail embodiment, one of the rails has transverse pressure contourization or edge blend and the other rail has a simple, wide air bearing surface located at the edge of the slider body for maximizing the distance between the rails. The combination of the two rails results in a stiffer slider with increased manufacturing yields.
