摘要：一个经改进的弓形扫描磁头装置与磁带传送线成一夹角。夹角、弓形扫描磁头装置的直径和磁头从弓形扫描磁头装置的磁头鼓端面凸出的尺寸的相对大小应使磁头在磁头鼓的一侧上面时与磁带可靠接触，当其在磁头鼓的另一侧上面时至多与磁带轻轻接触。最好是，在一侧可靠接触，在另一侧不接触；最好是，角度的大小可使磁头在接触一侧接触和脱离接触磁带时在磁带边沿留出一小段距离，以减轻或消除磁头压磁带边问题。另外，弓形扫描磁头装置可以是不倾斜的，但与其连用的盒式磁带可改成磁带成角度通过媒体存取孔传送。

摘要： A sloping tape guide is provided for an arcuately scanning tape drive so that tension per unit width of a magnetic tape is equalized in the head/tape contact zone on a front face of a head assembly of the arcuate scanner. The tape wraps over the circular edge of the magnetic head assembly. As a consequence, the tension per unit width is higher at the center of the tape that at the edges. The low tension at the edges of the tape results in poor head to tape contact in these regions and consequently unacceptable signal performance. This invention overcomes these difficulties by providing a means to equalize tension per unit width across the tape. The sloping tape guide has a front sloping flat surface which is bounded by top and bottom edges and first and second side edges, the first side edge being closer to the lat surface slopes rearwardly from its first edge to its second edge away from the periphery of the head assembly. The second edge is concave so that top and bottom edge portions of the sloping surface have a longer path length than a center portion of the sloping surface. By wrapping the tape around the second edge, the top and bottom edge portions of the magnetic tape traverse a longer tape path length than the middle portion of the magnetic tape thereby increasing tension per unit width at the edge portions of the tape as the tape makes transducing contact with the magnetic heads scanning across the width of the tape. Deadband portions at top and bottom edges of the tape are thereby eliminated to increase the efficiency of the arcuate scanner.
摘要翻译：为弧形扫描带驱动装置提供倾斜导带器，使得磁盘的每单位宽度的张力在弓形扫描仪的头组件的前表面上的头/带接触区域中相等。磁带卷绕在磁头组件的圆形边缘上。因此，在边缘处的带的中心，单位宽度的张力较高。磁带边缘的低张力导致这些区域的磁头与磁带接触不良，从而导致不可接受的信号性能。本发明克服了这些困难，通过提供一种均衡跨越带的单位宽度张力的方法。倾斜带引导件具有前倾斜的平坦表面，其由顶部边缘和底部边缘以及第一和第二侧边缘限定，第一侧边缘更接近拉头表面，从其第一边缘向后倾斜到远离其边缘的边缘的第二边缘头组件。第二边缘是凹形的，使得倾斜表面的顶部和底部边缘部分具有比倾斜表面的中心部分更长的路径长度。通过将带缠绕在第二边缘上，磁带的顶部和底部边缘部分比磁带的中间部分更长的磁带路径长度，从而在磁带的边缘部分增加每个单位宽度的张力与磁头的传感接触扫描磁带的宽度。从而消除了带的顶部和底部边缘处的死区部分，以提高弓形扫描器的效率。

摘要： An arcuate scan tape drive for transferring data to and from a data tape (26). Situated within a base (22) and cover (24) is a head carrier assembly (36) for recording data onto and playing back data from the data tape which advances in a longitudinal direction past the head carrier assembly. The head carrier assembly (36) includes an inside-out spin motor (40) for rotating the head carrier assembly and a pivot motor (72) at the rear of the head carrier assembly for pivoting the head carrier assembly in a plane perpendicular to the longitudinal direction of advancement of the tape (26). The spin motor (40) and pivoting motor (72) receive servo signals from a controller so as to continuously adjust the position of the core elements (46) with respect to the data tape so as to align the core elements with the arcuately-shaped data tracks (118).
