Abstract

981, 380. Magnetic video frequency recording &c. heads; local circuits for. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 17, 1963 [Dec. 20, 1962], No. 49768/63. Heading G5R. [Also in Division H1] A magnetic head for recording and/or playing back video information may be mounted on a rotatable shaft 1 (Fig. 1) carrying a core member 2 of a transformer in which windings 7 on a stationary core member 3 are coupled to windings 6 on the rotating core member 2 by arranging the windings 6 and 7 in the open ends of deep coaxial grooves 4 and 5. The core members may be spaced apart along the axis of rotation (Fig. 2) and may be made of iron laminations or of ferrite material.
