    • A data storage device for recording to and reading from magnetic thread includes a head assembly having an opening through which the magnetic thread passes. Transducing elements are positioned around the inner surface of the opening and interact with longitudinally-extending parallel tracks formatted around the surface of the magnetic thread. If the number of tracks is greater than the number of transducing elements, the transducing elements may be rotatable about the magnetic thread to position the transducing elements to interact with other tracks. The head assembly may open to aid positioning the magnetic thread within the opening in the head assembly during loading. If desired, multiple head assemblies may be placed in the thread path to improve data throughput. The magnetic thread may be formed with a non-circular cross-section and the opening in the head assembly may have a corresponding cross-section to reduce twisting of the magnetic thread as it passes through the opening.
    • 用于记录和读取磁性线的数据存储装置包括一个头部组件,其具有一个开口,磁性线穿过该开口。 传导元件围绕开口的内表面定位并且与围绕磁性线表面格式化的纵向延伸的平行轨道相互作用。 如果轨道的数量大于换能元件的数量,则换能元件可以围绕磁线旋转以将换能元件定位成与其它轨道相互作用。 头部组件可以打开以帮助在加载期间将磁性线定位在头部组件的开口内。 如果需要,可以将多个头部组件放置在线程路径中以提高数据吞吐量。 磁性线可以形成为非圆形横截面,并且头部组件中的开口可以具有相应的横截面,以减小磁性线穿过开口时的扭转。
