A first and second magneto-electric converting films, comprising for example, Hall elements, are vapor deposited onto a first and second highly permeable magnetic substances independently of each other. The resulting configuration is aligned so as to correspond with each track of a magnetic tape. A desired number of the magneto-electric converting films can be positioned parallel with each other. The resulting magnetic head with the multiple magneto-electric converting films is capable of producing a sustained reverberation or echo.
A multichannel magnetic head has magnetic circuits for respective channels, each positioned to traverse a magnetic flux to be detected and a Hall element disposed in the magnetic circuits and used as a magnetic-electric converter. The Hall element is an amorphous magnetic thin film which consists essentially of an alloy containing a rare earth element (e.g. Gd) and a transistion metal (e.g. Co). To the amorphous magnetic thin film there are connected a pair of current terminals and Hall voltage terminals. The Hall voltage terminals are provided in the same number as the number of channels.
A multichannel magnetic head has a Hall element which is disposed in a magnetic circuit which is traversed by a magnetic flux to be detected and which is used as magnetic/electric converting means. The Hall element comprises an amorphous magnetic thin film consisting of an alloy containing a rare earth element and a transition metal. To the amorphous magnetic thin film are connected a pair of current terminals and a plurality of Hall voltage terminals corresponding in number to the number of channels of the multichannel head, and the amorphous thin film is arranged in magnetic circuits of a plurality of channels.
