Abstract
A method of restoring a suspension of a hard disk drive includes detaching a slider, which is mounted on a tongue portion of the suspension via an adhesive, from the suspension, measuring a thickness of the adhesive in a cleaning area of the tongue portion, specifying a first residual area in which the thickness of the adhesive exceeds a threshold value, irradiating a first irradiation area including the first residual area locally with a first laser beam, and irradiating the cleaning area entirely with a second laser beam.

A method of restoring a suspension, the method comprising:
- detaching a slider, which is mounted on a tongue portion of the suspension of a hard disk drive via an adhesive, from the suspension;
- measuring a thickness of the adhesive in a cleaning area of the tongue portion;
- specifying a first residual area in which the thickness of the adhesive exceeds a threshold value;
- irradiating a first irradiation area including the first residual area locally with a first laser beam;
- and
- irradiating the cleaning area entirely with a second laser beam,
- wherein:
- the specifying the first residual area includes approximating the first residual area to a circle, and specifying a center and a diameter of the first residual area,
- the first irradiation area is a concentric circle slightly larger than the first residual area, and
- the first laser beam is applied in such a way as to fill in the first irradiation area.
A method of restoring a suspension, the method comprising:
- detaching a slider, which is mounted on a tongue portion of the suspension of a hard disk drive via an adhesive, from the suspension;
- measuring a thickness of the adhesive in a cleaning area of the tongue portion;
- specifying a first residual area in which the thickness of the adhesive exceeds a threshold value;
- irradiating a first irradiation area including the first residual area locally with a first laser beam;
- and
- irradiating the cleaning area entirely with a second laser beam,
- wherein:
- the tongue portion further includes a conductive line area surrounding the cleaning area, and a non-irradiation area formed between the cleaning area and the conductive line area, and
- the second laser beam is applied in such a way as to fill in the cleaning area at an interior side of the non-irradiation area.
