Abstract
Abstract A magnetic head supporting mechanism includes a head positioning actuator (223) having an arm (22), and a load beam (21) connected to the arm. The load beam has a gimbal (25). The gimbal includes a magnetic head slider fixing portion (30) on which a magnetic head slider (35) having a magnetic head is mounted, a first pair of beams (31, 32) extending from opposite sides of the magnetic head slider fixing portion along a traverse direction (38) of the load beam perpendicular to a longitudinal direction (37) thereof, and a second pair of beams (33, 34) respectively connected to the first pair of beams and extending so as to face the opposite sides of the magnetic head slider fixing portion. <IMAGE>
