Abstract
A thin-film magnetic head comprises an inductive type electromagnetic transducer having a first magnetic pole, a second magnetic pole, and a thin-film coil. A recording shield layer made of a magnetic material is formed on the side of the second magnetic pole opposite from the first magnetic pole. A recording shield gap layer made of a nonmagnetic material is formed between the second magnetic pole and the recording shield layer. By way of the recording shield gap layer, the recording shield layer covers at least both lateral parts of the second magnetic pole on the side of the second magnetic pole facing a recording medium.
