Abstract:
1. A head slider characterized in that, when an inertia force is generated, at an upstream position spaced apart by distance L 1 in the direction of air inflow end from a position where said inertia force is applied to said head slider, and at a downstream position spaced apart by distance L 2 in the direction of air outflow end from a position where said inertia force is applied, the membrane rigidities of air spring layer formed between said head slider and a recording medium are Kl and Kt respectively; and the amount of flying in a vertical direction from said recording medium at said downstream position is Xh, and the angle formed by the surface to be opposed to said recording medium of said head slider against said recording medium in stable flying of said head slider is θp, then the relationship is satisfied.
