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 above 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 (140-143, 153-156) 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 (82) for facilitating the wiring of the transducer coils (73, 74). The arm has an aperture (60) near the end which includes transducer (32) which permits access thereto during assembly. Insert cover (120) fits in the aperture and includes a lifting lab (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.
