Title: Innovations by Heng Qiao in Magnetic Read/Write Technology
Introduction
Heng Qiao is a notable inventor based in Dongguan, China. He has made significant contributions to the field of magnetic read/write technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
Heng Qiao's latest patents include methods for forming micro-texture on the air bearing surface of a magnetic read/write slider. One patent details a method that involves positioning sliders arranged in arrays on a tray, with each slider having a pole tip facing upward. The tray is then loaded into a processing chamber, evacuated to a preset pressure, and a processing gas containing oxygen is introduced. The sliders are exposed to etch the surface, forming a clear two-step structure. Another patent describes a method for forming micro-texture on the air bearing surface of a slider, which includes positioning sliders on a tray, evacuating the chamber, and introducing a mixture of inert gas and hydrocarbon gas. The mixture is ionized to produce ion beams that etch the sliders, creating a micro-texture with a two-step structure.
