Thin-film magnetic head and method of making where the head includes an antireflection film covering a leading shield
A thin-film magnetic head has a high write performance because its shape is smooth without roughness. The thin-film magnetic head includes a slider substrate, a write element and an antireflection film. The slider substrate has an air bearing surface at one side and supports a first support layer. The first support layer has a leading shield, and the leading shield has a low-level flat part, a slope part and a high-level flat part continuously arranged at one side in the recited order toward the air bearing surface. The antireflection film entirely covers the low-level flat part, the slope part and the high-level flat part of the leading shield. The write element has a recording magnetic pole film, and the recording magnetic pole film is formed above the antireflection film.
