UNIT OF ROTATING VIDEO HEADS Russian patent published in 1997 - IPC

FIELD: equipment for magnetic recording, in particular, home and professional video recorders. SUBSTANCE: device has two magnetic heads which are located on mounting plate and have C-shaped half-core, I-shaped half-core and winding which is passed through winding hole which is provided on C-shaped half-core. I-shaped half-cores face each other. Coils of winding of one head are coiled on both half-cores so that their number is reverse proportional to area of cross section of half- cores. In addition device has ring core which is made from ferromagnetic material and has screen, first winding which is shaped as closed coil and second winding which has several coils. Closed coil of first winding of core is passed through winding hole of second head and serves as winding of second head; terminals of second winding of core serve as terminal of second head. Area of winding hole of second head may be less area of winding hole of first head. Winding hole of second have may be made in I-shaped half-core which width is greater than width of I-shaped half-core of first head. EFFECT: increased functional capabilities. 3 cl, 3 dwg
