Abstract: A multiple-element magnetic head comprising a plurality of magnetic head half-members arranged in face to face relation with each other at opposing end surfaces, with magnetic gaps being formed between them. Such magnetic head half-members are each made by holding non-magnetic members of substantially inverted Ushape each including a horizontal portion and oppositely disposed vertical portions between magnetic members identical in shape and configuration with said non-magnetic members, holding the assembly between substantially U-shaped cores including a horizontal portion and oppositely disposed vertical portions, cutting off said horizontal portions of said non-magnetic members and said magnetic members while leaving said oppositely disposed vertical portions, and grinding end surfaces of said oppositely disposed vertical portions of the non-magnetic members and magnetic members at which the horizontal portions have been cut off so that said end surfaces may be flush with end surfaces of the cores which are to be positioned in face to face relation with end surfaces of cores of the other magnetic head halfmember.

Abstract: A magnetic head assembly comprises at least one resilient filmlike member held in tension over a drum-shaped support. A magnetic head holder and at least one head core are provided on an upper resilient member. The head core can follow the variation of contact caused by an uneveness of the magnetic surface of a magnetic medium.
Abstract translation: 一种磁头组件包括至少一个弹性薄膜状构件，该构件保持在鼓状支撑件上方。 一个磁头保持器和至少一个头部磁芯设置在上部弹性部件上。 磁头磁芯可以跟随由磁性介质的磁性表面的不均匀性引起的接触的变化。

Abstract: A magnetic tape recorder for television video signals uses two sequentially active magnetic heads mounted on a revolving disk. A commutator is arranged to rotate in synchronism with the revolving disk and to act as a program switch for selecting the magnetic head switching points and for controlling the associated circuitry. The program selectively changes the instantaneous electrical characteristics of a path leading from the heads to the associated circuitry, these changes occurring as a function of whether one or two heads is operative at the instant of change.
Abstract translation: 用于电视视频信号的磁带录像机使用安装在旋转盘上的两个顺序有效的磁头。 换向器被布置为与旋转盘同步旋转，并且用作用于选择磁头切换点并用于控制相关电路的程序开关。 该程序选择性地改变从磁头引导到相关联的电路的路径的瞬时电特性，这些变化作为一个或两个磁头在变化时刻是否起作用的功能而发生。
