ABSTRACT:
Fixture means and method for accurately positioning a carrier member or button with a magnetic slider head having a gap, in a carriage to be mounted in magnetic information storage equipment, particularly adapted for use with micro and mini computers. The fixture embodies a pair of parallel rods on which the carriage can be mounted for relative sliding movement. The fixture has a transparent panel at one end. The carriage is positionable in the fixture with the carrier button and the magnetic slider head directly underneath the transparent panel. A plunger and spring is provided in the fixture to provide a holding force against the magnetic slider head against the underside of the transparent panel. A video camera is provided having a lens with a reticle in it positioned with the optical axis aligned to provide an image of the magnetic gap. The camera is connected in closed circuit relationship with a television set or projector so that an image of the magnetic gap and the reticle appear on the display screen magnified 20 times. The operator then manually adjusts the button and the magnetic gap to orient the gap with reference to the image of the reticle in azimuth, track to track relationship and in indexed relationship.
