Magnetic head slider having spherical of ellipsoidal projection formed thereon |
摘要 |
Embodiments in accordance with the present invention provide a magnetic head slider capable of securing a larger flying margin even when position variations occur at the time of flying. Embodiments of the present invention also provide a magnetic head slider having an excellent flying following capability. A read element and a write element of a magnetic head slider are arranged on a spherical or ellipsoidal projection and this projection is formed on a thin film magnetic head part. This may prevent a flying margin from being reduced by variations in flying position and may prevent a manufacturing step from being caused on the spherical or ellipsoidal projection. Moreover, by making the constituent ratio of the thin film magnetic head part on an air-bearing surface of the magnetic head slider 100 to be 7% or more, the read element and the write element are arranged at a pressure center position on the center rail surface of the air-bearing surface. This may enhance a following capability when the slider flies.
