Abstract: A method of making a magnetic transducer head or element thereof from a binary alloy of silicon and iron, preferably containing from about 3 percent to 7 percent of silicon by weight, including provision of a grain-oriented silicon-iron core, annealing the core at a temperature above the Curie point in a dry hydrogen atmosphere and during cooling from that temperature subjecting the core piece to a magnetic field applied in the direction of the working flux at the core. The annealed core piece is formed so as to provide a gap-defining face for coupling to a magnetic record medium, the gap being of the order of about 1 micron.

Abstract: In the disclosed embodiments the video signal is recorded on successive longitudinal tracks with high frequency bias. The sound may be recorded transversely on adjacent tracks or may be recorded with the video as pulse modulation in the horizontal blanking intervals. The video bias frequency is selected so as to avoid beat notes with the video signal. The horizontal and vertical sync signals may be amplified separate from the composite video and then added thereto so as to record sync signals of increased amplitude. The picture signal from a television receiver may be recorded without further amplification.

Abstract: A magnetic tape apparatus wherein a capstan drive assembly provides a tape path thereabout and receives a transducer head with a convex face for scanning engagement with the tape. A magnetic shield may be interposed between the capstan and the head where the capstan is of magnetizable steel. The motor, flywheel and capstan form a unitary assembly which preferably includes a bearing for the outer end of the capstan. A endless loop or reel-to-reel tape cartridge configuration may be engaged with the capstan assembly without manual threading. Idler rollers for the capstan are of configuration to tension the tape at the transducer head location, and may be interchanged to tension the tape in either direction of movement. A preferred head is operable with bias of 10 megahertz or more.
