Embodiments of the invention avoid erasure of recorded data by
concentrating stray fields on a magnetic head element. According to one
embodiment, in a magnetic storage apparatus using a perpendicular
recording medium with a soft magnetic under layer, a soft magnetic shield
is provided so as to surround the upper parts and sides of magnetic head
elements. A distance between the soft magnetic shield and the medium is
shorter than that between the soft magnetic shield and the magnetic head
element.
