A fixture or fixtures and method for assembly and/or fabrication of a component of magnetic information storage apparatus. The component is a flexure arm carrying parts including a gimbal plate; transducer, that is, a magnetic slider head; and a flex cable connecting to the magnetic poles of the magnetic slider head. A fixture is provided having a configuration and holding pins for holding the magnetic slider head; for holding the gimbal plate, and a flexure arm with parts in aligned relationship, the fixture having a removable part which holds the gimbal plate and which is removable from the fixture for subsequent positioning of the flexure arm. Fixture parts are provided for configurating the flex cable. The method comprises a series of steps including positioning parts to be assembled in relationship to the fixture; taking out the removable fixture part; positioning the flexure arm and bonding and attaching the parts together to complete the fully assembled and fabricated component.

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.

Tooling and method for assembling parts of a component of a drive apparatus for disc records. A fixture is provided having a cavity for holding a carrier member or button for a magnetic slider head. The slider head is held in an opening in the button while in the fixture, the fixture establishing a predetermined relationship between the button and the slider head. A holding plate is provided with means for holding the parts in the fixture. The method includes the steps of providing the fixture, placing the slider head in the opening in the button, placing these parts in the fixture and holding them in predetermined relationship; applying bonding material to the slider head and the opening; holding the parts in the said relationship for a period of time, while the bonding material cures.
