    Abstract: A multistylus recording head having a plurality of recording styli with each stylus incorporating a multilayer magnetostrictive structure having two adjacent layers with opposing magnetostrictive properties for producing a bending of the stylus in the presence of a longitudinally applied magnetic field. One end of each of the styli is arranged along a recording line and adjacent to a magnetic boundary displacement structure to form a magnetic flux path therewith. The magnetic displacement structure is energized by an input signal to produce a selective displacement of a magnetic null in a composite magnetic field. The magnetic null is positioned with respect to the recording styli whereby a selected stylus is arranged to be in contact with a recording medium while the remaining styli are bent out of contact with the recording medium by effect of the remaining magnetic field.

    Abstract translation: 一种具有多个记录测针的多分辨率记录头，其中每个触针结合有具有相对的磁致伸缩特性的两个相邻层的多层磁致伸缩结构，用于在存在纵向施加的磁场的情况下产生触针的弯曲。 每个触针的一端沿着记录线布置并且与磁边界位移结构相邻以与其形成磁通路径。 磁位移结构由输入信号激励，以在复合磁场中产生磁零点的选择性位移。 磁零点相对于记录测针定位，由此所选择的触针被布置成与记录介质接触，而剩余的测针由于剩余的磁场而与记录介质弯曲脱离接触。
