Air bearing design producing steeper ramp profile near the laser texture zone

摘要

A dual etch depth slider air bearing surface includes a front pad disposed along the front and partially along the sides of the slider and a rear pad partially disposed along the rear of the slider, wherein a skewed center rail connects the front pad to the rear pad. Extending above the rear pad is a V-shaped ABS pad and extending above the front pad are two leading edge ABS pads that are separated by a channel towards the longitudinal center of the slider. The design enables the slider to fly much higher over the landing zone of the disk than at the data zone and provides for a steep take off profile followed by a rapid descend over the data zone.
