Abstract

PURPOSE:To realize uniform working and manufacturing with a constant load by making a distance between a suspension attaching surface and a magnetic head slider wide and causing sufficient plastic deformation at the time of a suspension bend working. CONSTITUTION:A suspension attaching surface 5 for attaching a suspension 1 to be used for holding a magnetic head slider 4 at one end to an arm 2 is made the inclined surface of a downward direction at a theta angle to a medium 3. The suspension 1 attached to the suspension attaching surface 5 is inverted from the downward direction to an upward direction and risen toward the medium 3 and thus, even when an interval between the arm 2 and the medium 3 is narrow, the sufficiently inverted deformation is realized and the uniform working and manufacturing are made possible with a constant load.
