Abstract

946,002. Frequency responsive playback heads. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 31, 1962 [Aug. 15, 1961], No. 29385/61. Heading G5R. [Also in Division G1] Frequencies present on a magnetic record tape 6 are analysed by passing the tape along a path parallel to the axes of a plurality of heads 2, each comprising an insulating core 1 close bifilar wound at a pitch corresponding to twice the wire diameter, and producing an output maximum when the record wavelength # equals the winding pitch, the frequency being determined from the known recording tape-speed.
