Abstract
An actuator assembly including an actuator arm, a suspension fixed to a front end portion of the actuator arm, and a head slider mounted on a front end portion of the suspension and having a magnetoresistive element. The suspension has a pair of first lead lines each of which has one end connected to the magnetoresistive element, and an easily removable short-circuit pattern for connecting the first lead lines with each other. The actuator assembly further includes a main FPC fixed at one end portion thereof to the actuator arm, and an interconnection FPC having a plurality of second lead lines for interconnecting the first lead lines and a wiring pattern of the main FPC. The interconnection FPC further has a plurality of ground lines for electrically connecting the second lead lines to the actuator arm. In using the actuator assembly in a magnetic disk drive, the short-circuit pattern is fused and each ground line is cut.
