Abstract: A method of manufacturing an electronic device includes a positioning step of positioning a first member supporting a laser diode with respect to a second member having a waveguide, a bonding step of bonding the first member and the second member together, and a checking step of checking the accuracy of positioning of the first member with respect to the second member. In the positioning step, the laser diode is energized to allow laser light to be emitted, and the laser light is allowed to be incident on the incidence end of the waveguide. In the bonding step, a bonding material is melted by irradiating the first member with heating light while the laser diode is not energized. In the checking step, the laser diode is energized again.

Abstract: In a conductive material supply apparatus that can connect a small slider electrode and a wiring electrode on a flexure in a miniaturized magnetic head, electrically conductive material is supplied, with the aid of flow of nitrogen gas that is pressurized to a first pressure, into the interior of a nozzle assembly that defines an interior space having a nozzle orifice through which the electrically conductive material can pass. After the electrically conductive material has been supplied, the flow of the nitrogen gas is stopped, and the interior space is temporarily brought into communication with the exterior space thereby decreasing the pressure in the interior space. Thereafter, nitrogen gas maintained at a second pressure that is designed to be lower than the first pressure is supplied to the interior space, whereby the electrically conductive material is ejected to the exterior from the nozzle orifice by the effect of the second pressure.

Abstract: A pallet main body is provided with a block holding member which presses a positioning surface of an actuator block against a block reference surface formed in the pallet main body, and a movable arm. An insertion member, which can be inserted between a plurality of opposing suspensions, is formed at a distal end of the movable arm. As a suspension to which a slider is to be attached contacts a first contact surface formed on the side in contact with this suspension, a distal end of the suspension to which the slider is to be attached is held at a prescribed height from the block reference surface, thereby forming a gap between this suspension and a suspension opposed to this suspension.

Abstract: Provided is a method of manufacturing a magnetic head with which bonding of a slider and a suspension can be performed by taking an ABS pattern, which determines flying characteristics, as a reference, with no special fabrication required on the slider or the suspension. The method relates to a method of manufacturing a magnetic head for attaching a slider, on which an air bearing surface (ABS) is formed, to a suspension. A surface of the slider on which the ABS is formed is photographed, and the ABS and an engraved region formed within the ABS are identified from the photographed image. Then, a reference that serves as a guide in attaching the suspension is computed, and the slider is attached to the suspension based on the reference. It thus becomes possible for positive pressure and negative pressure that occur in the ABS to be well balanced centered about the suspension, making it possible to stabilize flying attitude and electrical characteristics.

Abstract: After photographing a surface on which an ABS is formed, and the outer shape of a slider, the ABS and an engraved region formed within the ABS are identified from a photographed image. A reference that becomes a guide for attaching to a suspension is then computed, and a positional relationship between the reference and the outer shape of the slider is stored as association information. Next, the outer shape of the slider is measured, and measured values are compared to the association information and a reference is read out when attaching the slider to the suspension. An adhesive is discharged, from below, onto a suspension attachment surface of the slider based on the reference. The slider may then be attached to the suspension while holding the slider in a state where the ABS is positioned on an upper side of the slider.

Abstract: A method of manufacturing a magnetic head, and a magnetic head manufacturing apparatus, are provided, which make it possible to post mount a slider to a suspension even when the suspension and an actuator block are assembled together in advance, thus preventing the slider from being destroyed due to ESD or the like. First, a plurality of opposing suspensions are pushed open, forming a gap having a prescribed height between distal ends of the suspensions to which the slider is to be attached. Both side surfaces of the slider are then gripped by pressing surfaces formed on a gripping mechanism. An ABS of the slider is made to contact a horizontal regulating surface formed on the gripping mechanism, thus regulating the horizontal attitude of the slider. The slider, which is gripped by the gripping mechanism, is then inserted into the gap. A rear surface of the slider is attached to the distal end of the suspension through a connecting member.
