In-contact magnetic head slider with multiple surface levels for creating multiple positive and negative pressure regions

摘要

A magnetic head structure is formed on an air-bearing surface thereof including first, second and third surfaces located in order in a height direction from a level closest to the magnetic recording medium so as to form negative and positive pressure-generating regions. The structure includes a first positive pressure-generating region having the second and first surfaces formed at a central portion along a longitudinal direction thereof, a first negative pressure-generating region having the third surface formed on a side of an air inlet edge with respect to the first positive pressure-generating region and a second negative pressure-generating region having the third surface formed on a side of an air outlet edge with respect to the first positive pressure-generating region.
