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： On a surface of a bottom pole, a write gap film and first magnetic material film having a high saturation magnetic flux density are formed, and the first magnetic material film is etched to remain a portion extending from an air bearing surface to a throat height zero reference position and a first non-magnetic film is formed in a removed portion. The first non-magnetic material film is polished to obtain a flat surface which is coplanar with a surface of the first magnetic material film. A second magnetic material film having a high saturation magnetic flux density is formed on the flat surface. The second magnetic material film, first magnetic material film, write gap film and bottom pole are partially removed by RIE using a mask formed on the flat surface in accordance with a given pattern to form a track pole having a double-layer structure consisting of bottom and to track poles and a trim structure in a self-aligned manner. A second non-magnetic material film is formed in a space formed by the etching, and a surface of the second non-magnetic material film is polished to have a flat coplanar surface with the top track pole. A thin film coil is formed on the flat surface, and a top pole is formed such that one end is magnetically coupled with the top track pole and the other end is magnetically coupled with the first pole.

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 thin-film magnetic head is manufactured as follows. First, a base insulating layer having a magnetic pole forming depression sunken into a form corresponding to the main magnetic pole layer is formed, a stop film for CMP is formed such as to fill the magnetic pole forming depression, and then a magnetic layer is formed on the stop film. Next, the magnetic layer is separated by forming a separation groove substantially surrounding the magnetic pole forming depression on the outside thereof, and thus separated magnetic layer is formed with a cover insulating film adapted to cover the whole upper face. The surface is polished by CMP until the stop film is exposed, so that the part of magnetic layer remaining on the inside of the magnetic pole forming depression is used as the main magnetic pole layer. Further, a recording gap layer, a write shield layer, and a thin-film coil are formed.
