    Abstract: Apparatus for accurately positioning a transducer head relative to parallel tracks on a recording medium such as magnetic tape. The apparatus includes a frame having a guide to direct the tape along a horizontal path past the transducer head, and a cam mounted for rotation on the frame. The cam has a cylindrically shaped upstanding portion in which a series of graduated planar steps is formed, each such step corresponding to a separate track on the tape. The apparatus further includes a lever having one end pivotally mounted to the frame and a remote end positioned to bear on one of the steps of the cam, and a platform assembly which carries the transducer head and which bears on a mid-portion of the lever. Rotation of the cam raises or lowers the remote end of the lever by a controllable number of steps, and thereby raises or lowers the transducer head by a corresponding but lesser amount, to align it with a selected track on the tape. Fine adjustment of the alignment of the transducer head with respect to the center of a track on the tape is accomplished by a mechanism for movement of the relative location of the pivoted end of the lever.

    Abstract translation: 用于在诸如磁带的记录介质上相对于平行轨道精确地定位换能器头的装置。 该装置包括具有引导件的框架，该引导件沿着水平路径引导带通过换能器头部，以及安装成用于在框架上旋转的凸轮。 凸轮具有圆柱形的直立部分，其中形成一系列刻度的平面台阶，每个这样的步骤对应于带上的单独的轨道。 该装置还包括杠杆，其一端可枢转地安装在框架上，远端位于承载在凸轮的一个台阶上的平台组件，以及承载换能器头部并承载在杠杆的中间部分上的平台组件 。 凸轮的旋转可以通过可控数量的步骤升高或降低杠杆的远端，从而将换能器头部升高或降低相应但较小的量，以使其与带上的选定轨道对准。 换能器头相对于磁带上的轨道中心的对准的微调是通过用于使杠杆的枢转端的相对位置移动的机构实现的。
