Manufacturing method of a disk drive suspension

A manufacturing device of a disk drive suspension, the disk drive suspension comprising a load beam which comprises a dimple and a flexure which includes a tongue opposed to the dimple and an outrigger connected to the tongue, and the manufacturing device comprising:

• a laser irradiation device configured to irradiate a first laser beam and a second laser beam to the outrigger;
• and
• a controller configured to control the laser irradiation device,
• wherein:
• the controller is configured to execute processes comprising:
• a first setting process of setting a first position within a first region on the outrigger at which a bent portion bent in a thickness direction is to be formed by irradiation of the first laser beam;
• a process of measuring, before forming the bent portion at the first position, initial values of a pitch angle and a roll angle of the tongue;
• a process of calculating, before forming the bent portion at the first position, predicted values of the pitch angle and the roll angle of the tongue that are predicted to result after the bent portion is formed at a first position, the predicted values being calculated based on (i) the initial values measured in the measuring and (ii) predicted amounts of change of the pitch angle and the roll angle before and after the bent portion is formed at the first position;
• a second setting process of setting, before forming the bent portion at the first position, a second position on the outrigger, the second position being set within a second region different from the first region, and the second position being a position to which the second laser beam is irradiated to make the predicted values approximate to predetermined target values;
• and
• an irradiation process of, based on the first position and the second position having been set, controlling the laser irradiation device to irradiate the first laser beam to the first position to form the bent portion, and to irradiate the second laser beam to the second position.
