Abstract
In a head slider, when the distance between the upstream position and the downstream position in a direction parallel to the surface of the recording medium is L, and the amount of flying in a vertical direction from the recording medium at the downstream position is Xh, and the angle formed by the surface to be opposed to the recording medium of the head slider against the recording medium in stable flying of the head slider is θp, then the relation of(L tan θp/Xh)≦((Kt/Kl)−1)is satisfied for membrane rigidities Kl and Kt. By such configuration of a head slider, when inertia force caused by external impact or the like is applied to the head slider, air layer formed between the air bearing surface of the head slider and the recording medium surface acts as an air spring while the head slider rotates in the pitch direction.
