Abstract: A flux sensitive magnetic head is disclosed which comprises conductive electrodes formed contiguous to the principal surface of a semiconductor substrate at a predetermined spacing, the electrodes being formed by evaporating or diffusing a conductive material on or into the substrate, and a flux sensitive element bridging the electrodes. This head may have a small size and is suited for constructing multi-track heads.

Abstract: A multi-tracks magnetic head has a first conductor utilized as the bias winding, and a second conductor as the winding for the signal to be recorded. Only the first conductors of the respective unit magnetic heads are connected in series.By making use of the multi-track magnetic head constructed in this way, electrical power consumption by the amplifiers supplying the recording currents to drive all the composing unit magnetic heads is minimized, and the magnetic cross-talk between the unit magnetic heads is reduced.

Abstract: A television signal recording and reproducing system wherein a television signal to be recorded is sequentially sampled at a predetermined number of points during each horizontal scanning period thereby to convert the television signal occupying a wide band into substantially vertically scanned signals. The converted signals, which have also been divided into multichannel signals, are recorded on a recording medium with a multichannel magnetic head. Reproduced signals from the multichannel head are sampled and added to produce the original television signals in a similar but reverse operation to the recording operation.
