摘要： According to an embodiment of the present invention, a slider design is presented that provides improved protection for the head/sensor of the slider. In one embodiment, the design of the slider is such that ESD protection is provided during the slider wafer process, the “back-end” processes (e.g., when the completed slider/head is incorporated into an HGA), and during operation in a disk drive or the like. In this embodiment, a conductive film is provided that surrounds the insulating-material slider substrate. The conductive film provides a grounding path during the wafer fabrication processes. This conductive layer may be further patterned during head fabrication to provide a ground path for back-end fabrication processes. A conductive stripe may be added for discharging debris in the slider-to-disk interface.

摘要： A winding stem mechanism including a winding shaft having a detent portion comprised of a pair of annular peripheral recesses with an annular step portion therebetween, and a pair of annular stops each adjacent a respective one of the recesses, and mounted for rotation and for being axially slidable. A resilient spring-like member normally engages a first of the recesses to define a normal position of the shaft and when the shaft travels in a first axial direction the spring-like member climbs the annular step portion to engage the second of the recesses. When the shaft travels in a second axial direction it pushes the annular stop adjacent the first recess to flex the spring-like member to permit the shaft to travel to a second operating position and flex in a direction effective to bias the shaft back from the second operating position to the normal position when the shaft is released.

The second and fourth sidewalls are close to perpendicular to the top surface of the substrate. Each of the second and fourth sidewalls has an edge farthest from the top surface of the substrate, the edge being parallel to the medium facing surface. The main pole has a first, a second, a third and a fourth side surface. The first side surface is opposed to the first sidewall. A portion of the second side surface is opposed to the second sidewall. The third side surface is opposed to the third sidewall. A portion of the fourth side surface is opposed to the fourth sidewall.

摘要： A magnetic head includes a main magnetic pole, a shield having an end face located in a medium facing surface to wrap around an end face of the main magnetic pole, and a gap part provided between the main magnetic pole and the shield. The shield includes a bottom shield, two side shields, and a top shield. The gap part includes first and second gap layers. In a manufacturing method of the magnetic head, a mold is formed on the top surface of the bottom shield, the mold having a shape determined by photolithography and being intended to be removed later. Next, the two side shields are formed on the top surface of the bottom shield by performing plating without forming a seed layer. Next, the mold is removed and then the first gap layer, the main magnetic pole, the second gap layer, and the top shield are formed in succession.

摘要： ABSTRACT A simple method is provided for protecting slider mounted read/write transducers from electrostatic discharge damage during the manufacture of disk drives. The method involves placing a ball of conducting thermoplastic resin, such as a gold or silver epoxy, between the terminal pads of the transducer and using the ball to shunt the pads to read-head shields and the slider substrate and thence to ground. The epoxy ball is easily applied and easily removed and can be used at different stages in the manufacturing process.
