Claims
- 1. A method for manufacturing a magnetic head having a slider and a thin-film device, said slider having an air groove and a facing surface facing a recording medium, said thin-film device for at least one of storing and playing back a magnetic record on said recording medium, said thin-film device being provided at an end portion of a trailing side of said slider, said method comprising the steps of:forming a groove portion on a substrate that serves as a base material for said slider, said groove portion being formed by machining; providing a resist layer which defines the facing surface of said slider adjacent said groove portion on a surface of said substrate; forming a first step portion at a region from said facing surface to said groove portion by etching a surface area not covered with said resist layer, said etching accomplished by using an ion milling system; and cutting said substrate at said groove portion so that a second step portion is formed adjacent to an outer end portion of said first step portion.
- 2. A method for manufacturing a magnetic head according to claim 1, wherein said second step portion is formed by machining.
- 3. A method for manufacturing a magnetic head according to claim 1, wherein an angle θ defined by a first plane of said facing surface and a second plane containing an outer edge of said first step portion and an outer edge of said second step portion ranges from 45 to 90 degrees.
- 4. A method for manufacturing a magnetic head according to claim 1, wherein said second step portion is provided at an end portion of a leading side of said slider.
- 5. A method for manufacturing a magnetic head according to claim 1, wherein said outer end portion of said first step portion has a rounded configuration.
- 6. A method for manufacturing a magnetic head according to claim 1, wherein at least one of a corner portion of said end portion of a leading side and a side panel of said slider and a corner portion of said end portion of said trailing side and said side panel of said slider is shaved.
- 7. A method for manufacturing a magnetic head according to claim 6, wherein said corner portion has a rounded configuration.
