ABSTRACT:
A thin film magnetic head having a slider and a magnetic transducing element for reading, wherein the slider is provided with an air bearing surface; the magnetic transducing element for reading includes conductor films, a magnetoresistive element and magnetic shield films and is provided on the slider; the conductor films are composed of two conductor films contiguously arranged interposing a first spacing and a second spacing, the first spacing being disposed on the side of the air bearing surface specifying a track width, the second spacing being disposed on the backward side of the first spacing; the magnetoresistive element is connected between the first and the second conductor films crossing the first spacing; the magnetic shield films include a lower magnetic shield film and an upper shield film, the lower magnetic shield film being located on the lower side of the conductor films and the magnetoresistive element and the upper magnetic shield film being located on the upper side of the conductor films and the magnetoresistive element; and the conductor films are arranged so that a size of the second spacing is equal to or less than 10 .mu.m.
