    摘要: The method of manufacturing a thin-film magnetic head in accordance with the present invention comprises the steps of forming a first magnetic pole layer; removing both sides in a track width direction of the first magnetic pole layer so as to leave a predetermined residual area in the first magnetic pole layer; forming an insulating layer about the residual area of the first magnetic pole layer; forming a gap layer made of a nonmagnetic material; forming a second magnetic pole layer magnetically connected to the first magnetic pole; and patterning the second magnetic pole layer by etching while using a mask. As a consequence, even if an area relatively far from the second magnetic pole layer is eliminated from the gap layer, the insulating layer is mainly exposed from this area. This can prevent magnetic materials from adhering to the root of the second magnetic pole layer and its vicinity during etching.

    摘要: A reproducing head of a thin-film magnetic head incorporates an MR element, a pair of bias field applying layers located to be adjacent to the side portions of the MR element, and a pair of electrode layers that are located on the bias field applying layers and overlap the MR element. The electrode layers each have a first layer that is laid over part of the top surface of the MR element via a protection layer, and a second layer that overlaps the first layer. In the method of manufacturing the reproducing head, after forming the protection layer on an element-to-be film to make the MR element, a first electrode-to-be film to make the first layers is formed continuously without interposing a step of exposing the protection layer to the air.

    摘要: A slider comprises a slider body and a head element. The slider body has an air bearing surface, an air inflow end and an air outflow end. 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.
