VSESOJUZNY NAUCHNOISSLEDOVATELSKY INSTITUT MAGNITNOI ZAPISI I TEKHNOLOGII RADIOVESCHANIA I TELEVIDENIA. 28 March, 1967 [28 March, 1966; 6 July, 1966], No. 14134/67. Heading G5R. A combination magnetic head for magnetic recording of electric signals and simultaneous checking of the recorded information comprises a composite magnetic circuit consisting of two symmetrical half-cores 1, 8, a middle core 3 and two working gaps 4, 9, an additional magnetic circuit comprising a separate core member 7 with a reproducing winding 6 being built-in between core 3 and half-core 8, a winding 2 being arranged on half-core 1 for recording a signal. The middle core 3 may be composed of several parts (3), (3<SP>1</SP>), Fig. 3 (not shown). |
