Abstract
A method for forming micro-texture on ABS of a slider, includes steps of: positioning sliders arranged in arrays on a tray, each slider having a pole tip facing upward; loading the tray into a processing chamber, and evacuating the processing chamber to a preset pressure; introducing a mixture gas of inert gas and hydrocarbon gas into the processing chamber, and ionizing the mixture gas to produce ion beams; exposing the sliders to the ion beam for etching so as to form micro-texture with two-step structure on the ABS of the slider. The invention also discloses a method of manufacturing a slider having micro-texture.
