ABSTRACT:
A head slider includes a parallelepiped-shaped slider base having a flat flying surface. A flat first step is formed at an air inlet end of the flying surface to be stepped from the flying surface. A flat second step is formed on the first step to be stepped from the flying surface. A vacuum area is formed at a downstream end of an air flow flowing from the first and second steps on the flying surface. At least one groove is formed on a portion of the first step for introducing air to the vacuum area. The width of the groove at the air inlet end and the width of the groove at an air outlet end can differ from each other. A trailing edge of the first step can be closer to a trailing edge of the slider base than a trailing edge of the second step.
