Abstract
A slider for magnetic recording includes at least one ski with a front portion and a rear portion, a read and/or write head located at the rear portion of the slider, the front portion of each ski having first and second steps with, respectively, first and second risers. The first riser of the first step forms with a longitudinal direction of the ski a first angle of between approximately 10.degree. and approximately 60.degree. and the second riser of the second step forms with the longitudinal direction of the ski a second angle which differs from the first angle and is between approximately 20.degree. and approximately 80.degree.. The height of the first riser is between approximately 20 nm and approximately 200 nm and the height of the second riser is between approximately 200 nm and approximately 2 .mu.m.
