According to an embodiment, a slider of a head comprises a negative-pressure cavity formed in a facing surface, a leading step portion situated on an inflow side of the negative-pressure cavity, a pair of side portions opposed to each other, a trailing step portion situated on an outflow side of the negative-pressure cavity, a leading pad provided on an end portion of the leading step portion on the negative-pressure cavity side, and a plurality of recesses formed on the inflow side of the leading pad and individually opening in the inflow-side end face. The leading step portion includes a main step portion which is situated beside the inflow side of the leading pad and extends in a second direction, and at least one extended step portion extending transversely to the second direction from the main step portion toward the inflow side and situated between the recesses.
