Latest Patents

One of his latest patents is a method to protect a GMR head from electrostatic damage during the manufacturing process. This method involves placing a ball of conducting thermoplastic resin, such as a gold or silver epoxy, between the terminal pads of the transducer. This innovative approach helps shunt the pads to read-head shields and the slider substrate, ultimately grounding the system. The epoxy ball is easily applied and removed, making it versatile for different stages of the manufacturing process.

Another notable patent is a method to improve crown sigma control of the slider in a hard disk drive. By lapping the backside of the slider to a smooth convex contour similar to the ABS shape, the sensitivity of the ABS shape to temperature variations is greatly reduced. This results in tighter distribution of ABS shapes, thereby enhancing disk drive reliability.
