The air bearing surface has: a first surface including two portions extending in a direction of air passage; a second surface including a portion disposed between the two portions of the first surface; and a third surface located closer to the air outflow end than the first surface is. The first surface and the second surface have such a difference in level that the second surface is located farther from a recording medium than the first surface is. The difference in level varies gradually so as to increase with decreasing distance from the air outflow end. A method of manufacturing the slider includes forming a slider material containing a portion to be the slider body and the head element, and processing the material so as to form the air bearing surface.

摘要： A track width defining layer includes: a track width defining portion having an end located in the air bearing surface and the other end located opposite to the air bearing surface; and a wide portion coupled to the other end of the track width defining portion. The track width defining layer is formed by frame plating. A frame is formed by exposing and developing a resist layer. The step of exposing the resist layer includes: a first exposure step for forming a first latent image in the resist layer; and a second exposure step for forming a second latent image in the resist layer. The first latent image is made up of a first portion corresponding to the track width defining portion and a second portion adjoining the first portion and extending along the contour of the wide portion. The second latent image is intended for use in combination with the first latent image so as to form a latent image corresponding to the track width defining layer, and does not include a portion corresponding to the track width defining portion.
