Abstract: A housing apparatus is operable to align a record/playback head with respect to different parallel tracks on a moving magnetic tape in such a manner as not to disturb the positioning of the tape as it passes longitudinally along its transport path. The housing apparatus includes a housing body having a convex, rounded front face lying in contacting relation with respect to the moving magnetic tape at two closely spaced-apart areas. A record/playback head is transversely movable with respect to the housing body and extends through a provided opening in the body to lie in contact with the moving tape between the two tape contacting areas of the housing body front face. Means is provided to move the record/playback head transversely with respect to the tape while the moving tape is in contact with these two areas on either side of the head.
Abstract translation: 壳体装置可操作以使记录/重放头相对于移动的磁带上的不同的平行轨迹对齐，以便当磁带沿其传送路径纵向通过时不会干扰磁带的定位。 壳体装置包括壳体，该壳体具有在两个相互间隔开的区域处相对于移动磁带处于接触关系的凸形圆形前表面。 记录/回放头可相对于壳体主体横向移动，并延伸穿过主体中的设置开口以与壳体主体前面的两个带接触区域之间的移动带接触。 提供了用于相对于带横向移动记录/重放头的装置，同时移动带与头部两侧的这两个区域接触。
