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.

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.
