Abstract: PROBLEM TO BE SOLVED: To enable center lines of respective members to be aligned correctly by allowing a first reference point to have a V-shaped edge and arranging the first reference point at a position adjacent to a dimple for making an assembly perform a gimbal type movement, arranging a second reference point adjacently to the spacer mounted to the pivotal center of an arm member and arranging a third reference point adjacently to the front end of the arm member. SOLUTION: A head supporting arm 15 is positioned with respect to a rotary data recording disk 21 and is inclined from a line vertical to a center line 25 by an angle θ in order to make the distance between the center of an opening 19 and the center of the disk 21 minimum. Slots of an arm member and the opening 19 are used in order to align respective center lines of the arm member, a suspension load arm beam and an integration type wiring plate. Long thin slots 30 and 33 are used as reference points aligning center lines of the head supporting arm 15 and the dimple 50 of the suspension load beam and the center line of a head/slider assembly 20.

Abstract: PROBLEM TO BE SOLVED: To provide a method for washing the entire part of a laminated actuator arm assembly after the end of solder connection. SOLUTION: This washing method has a stage for aligning and laminating one or plural head/suspension assemblies 51 and one or plural spacers 53, 54, a stage for forming a first sub-assembly by fixing the laminated head/suspension assemblies and the spacers, a stage for forming the second sub-assembly by connecting the lead wires of the first sub-assembly and a flexible cable 76, a stage for washing the second sub-assembly and a stage for mounting a pivot 71 to the washed second sub-assembly.

Abstract: PROBLEM TO BE SOLVED: To simplify wiring processings and to enhance workability by making extension plates bendable in a direction vertical to the flat surfaces of arms and arranging plural arms bedable around two axes of the flate planes of the arms, plural first connection pads to be provided on respective extension plates and plural second connection pads to be provided on the flat surface of a circuit board. SOLUTION: A voice coil motor 12 is attached to an arm assembly 10 and head/slider assemblies 13 are moved in the radial direction by the voice coil motor 12 by connecting respective rear ends of arms 11 to an axis 14 while pivotally attaching them to the frame of a disk driving device. Moving amounts of second connection pads being on a circuit board 23 with respect to extension plates 19 are small and positions of the pads are correctly formed and at the time the extension plates 19 are rotatingly moved around three axes orthogonal with each other, the pads are not fluctuated and the extension plates 19 can be bent in the direction vertical to flat surfaces of the arms 11 and the arms 11 can be moved around two axes of the flat surfaces.
