Abstract
A head suspensionincludes a base plate, a load bend, a load beam, a flexure, and a sliderthat are assembled together through several processes including a pressing process. In such a head suspensionthat is a finished product in a conventional sense, a front endof the base plateis twisted so that the front endinclines toward one of inner and outer circumferences of a disk-like recording medium. The twisting process is carried out before attaching the head suspensionto an armof a carriage to be installed in a hard disk drive. The head suspensionwith the twisted front endprevents off-track errors even when it is used for a multi-arm assembly involving a plurality of head suspensions.
