Claim Text:
1. An apparatus for attaching a submount assembly to a slider, the submount assembly including a submount and a laser diode on the submount, the submount including a first surface, the slider including an air-bearing surface (ABS) and a transducer, the apparatus comprising: an optical fiber configured to carry a laser pulse; and a holder including a vacuum channel therein, an optical fiber aperture therein, and a second surface having an aperture for the vacuum channel therein, a portion of the optical fiber being held in the optical fiber aperture, the vacuum channel being configured to hold the first surface of the submount against the second surface of the holder by a pressure differential between a pressure developed in the vacuum channel and an external pressure at a remaining portion of the submount assembly, the pressure in the vacuum channel being less than the external pressure, the laser diode being attached to a third surface of the submount different from the first surface, the submount including a fourth surface adjoining and at a first angle from the first surface, the holder further including a notch therein, the notch including the second surface of the holder and a fifth surface at a second angle from the second surface, the notch being configured such that the vacuum channel holds the first surface of the submount against the second surface of the notch and holds the fourth surface of the submount against the fifth surface of the notch, the third surface of the submount being opposite to the fourth surface of the submount.
