A pair of slits are defined in a slider body of a head slider so as to
extend from a trailing end surface to the leading end on the slider body.
A movable block is established in the slider body between the slits. The
slits ensure the extent of movement for the movable block. Elongated
plates enable a relative displacement between the movable block and a
stationary block. A head element is mounted on a trailing end surface of
the movable block. The thickness of a non-magnetic layer corresponds to
the gap length of the head element. The gap length of the head element
can easily be controlled based on deposition of the non-magnetic layer.
The thickness of the non-magnetic layer can be reduced in a relatively
facilitated manner, so that the gap length of the head element can easily
be minimized.
