ABSTRACT:
An electromagnetic transducer assembly includes a carriage 30 carrying a first transducer 33 projecting therefrom and a load arm 35 carrying a second transducer 32 arranged for gimballing movement about a pair of mutually perpendicular axes, the arm being connected to the carriage by a leaf hinge assembly 43 for movement to load or unload transducer 32 to the disk recording medium 20. The transducers have planar disk engaging faces surrounded by edge bevels which merge smoothly with each other at conical corner surfaces 144, 157, and which are blended smoothly into the faces. The second transducer 32 is mounted in the arm on a flexure member 65, which also mounts a connector block 75 to which a flex strip 81 is connected, and which includes eyelet pins for facilitating the wiring of the transducer coils. The arm has an aperture 60 near the end which includes transducer 32 which permits access thereto during assembly. Insert cover 120 fits the aperture and includes a lifting tab 122, and an adjustable pivot member 133 for the gimballing of the transducer. The base includes ramps 160, 161 for facilitating the insertion and removal of a diskette 21 into operative position with respect to the transducers. The hinge assembly includes a leaf spring 44 and means 45-47, 52, 53 clamping it to the arm and to the base. A spring 55 urges the arm in a first direction about the hinge, and acts as a cover for passages 83-86 leading a connection cable 80 to the flex strip.
