Abstract

844,050. Magnetic recording and reproducing heads. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 9, 1959 [April 12, 1958], No. 12024/59. Class 40 (2). Apparatus for recording or reproducing highfrequency signals such as television signals comprises a high-speed rotating wheel consisting of pole pieces 1, 2 traversed by a magnetic flux associated with a current conductor 5 passing through the wheel and carrying the signal currents. The high-speed wheel could comprise three gaps 6, as shown in Fig. 2. The edge of the wheel could engage a curved tape, as shown in Fig. 3, or the face of the wheel could engage a flat tape passed over a roller 8, as shown in Fig. 4. Specification 760,874 is referred to.
