摘要 |
A thin-film magnetic head comprises: a magnetoresistive element: first and second read shield layers disposed to sandwich the magnetoresistive element; and bias field applying layers for applying a bias magnetic field to the magnetoresistive element. Each of the first and second read shield layers has: a first end face located in a medium facing surface; a second end face opposite to the first end face; a first width changing portion that continuously decreases in width as the distance from the first end face decreases; and a second width changing portion that continuously decreases in width as the distance from the second end face decreases.
