Abstract:
A slider is formed with an ABS topography that eliminates the accumulation of lubricant swept from the surface of a rotating disk in an operating HDD. The topography includes air channeling grooves in which are formed backflow blocking elements that prevent the formation airflow patterns that would cause lubricant to be aspirated into the ABS topography of the slider and that create airflow patterns that sweep lubricant away from the ABS of the slider. The topography is first tested to make sure that the slider has the proper flying height and aerodynamic stability, then the backflow blocking elements are added to control the airflow, while maintaining the desired flying height and stability.
