Patent number: 7145752Abstract: 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/S2 is 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.Type: GrantFiled: April 5, 2004Date of Patent: December 5, 2006Assignee: Alps Electric Co., Ltd.Inventors: Junsei Ueda, Hirohisa Ishihara, Yasuyuki Kondo, Satoshi Morikawa, Keishi Nakashima
