Abstract

1373687 Transducing heads M E GERRY 20 March 1972 9554/72 Heading G5R A magnetic head core 2, having a gap 10 for recording on a tape 9, has wound thereon two coils L z , L w respectively for the production of audio frequency flux # z and high frequency bias recording flux # w , and the coils, the core, and a back-gap 3 are so arranged that the coefficient of coupling between the coils is less than 0À9. A similar system (Fig. 3, not shown) is used for playback. In the arrangements of Figs. 4, 5, 6 (not shown), U-shaped core members having discontinuities therein are stated to act as single turn coils.
