Abstract:
According to one embodiment, a magnetic head includes a protective layer. When an element unit is a magnetic recording element unit, the protective layer includes a first region on a magnetic recording element protrusion and a second region on a magnetic recording element shield, the first region and the second region being flush with each other, or the first region being recessed more than the second region. When the element unit is a magnetic reading element unit, the protective layer includes a third region on a magnetic reading element protrusion and a fourth region on a magnetic reading element shield, the third region and the fourth region being flush with each other, or the third region being recessed more than the fourth region.
