Abstract
A slider utilizes a triple-etch, high pitch-stiffness side rail ABS design. The slider is characterized by a relatively deep shallow recession at its leading edge, which maximizes the cavity area while at the same time increases the pitch angle to achieve DLC pad clearance as required by smooth media ABS designs. The slider ABS has a shallower recession at the trailing edge, which provides low gram-load sensitivity and low flying standard deviation. The slider ABS further presents a decreased sensitivity in response to altitude variations.
