ABSTRACT:
A magnetic head apparatus including a magnetic head slider having an overall front half region area (S) and a step surface area (S1) and a positive-pressure generating surface area (S2) both in the front half region, such that the area ratio S1/S is about 0.180 to about 0.232 and the area ratio S1/S2is about 0.30 to about 0.47. With this arrangement a difference in pitch angles of the magnetic head slider at the moment when it is just levitated and during levitation is large, and a variation of the pitch angle due to a pressure change is small, thereby preventing damage to a magnetic element within the magnetic head slider while achieving a stable levitation attitude of the magnetic head slider.
