A head suspension 15 includes a base plate 27, a load bend 35, a load beam 37, a flexure 39, and a slider 25 that are assembled together through several processes including a pressing process. In such a head suspension 15 that is a finished product in a conventional sense, a front end 30 of the base plate 27 is twisted so that the front end 30 inclines toward one of inner and outer circumferences of a disk-like recording medium 33. The twisting process is carried out before attaching the head suspension 15 to an arm 13 of a carriage to be installed in a hard disk drive. The head suspension 15 with the twisted front end 30 prevents off-track errors even when it is used for a multi-arm assembly involving a plurality of head suspensions.
