Data storage tape cardridge with reinforcing tape reel lock

一种具有增强带盘锁定器的数据存储磁带盒。数据存储磁带盒包括一个划分为第一外壳部分和第二外壳部分的外壳，一个从第一外壳部分内表面延伸出来的中心轴，一个由中心轴可旋转地保持的带盘组件和一条围绕带盘组件卷绕的存储磁带。带盘组件包括一个毂，相对的磁带法兰盘，和一个制动体。毂包括一个在内部固定到柱的磁带安放部分，柱限定一个大小可安放中心轴的轴向孔。制动体可伸缩地与毂的一个轴端相联，包括一个制动面和一个内支撑面。形成制动面，是用于同第二外壳部分选择性地啮合。形成内支撑面，是为了紧贴毂的柱。在锁定状态，制动体防止毂旋转并限制柱左右移动，于是限制中心轴左右偏斜。 A data storage tape cartridge having a reinforcing tape reel lock. The data storage tape cartridge includes a housing defined by a first housing section and a second housing section, a hub pin extending from an interior surface of the first housing section, a tape reel assembly rotatably maintained by the hub pin and a storage tape wrapped about the tape reel assembly. The tape reel assembly includes a hub, opposing tape flanges and a brake body. The hub includes a tape receiving portion interiorly secured to a post, the post defining an axial bore sized to receive the hub pin. The brake body is retractably associated with an axial end of the hub and includes a braking surface and an interior support surface. The braking surface is configured for selective engagement with the second housing section. The interior support surface is configured to abut the post of the hub. In a locked position, the brake body prevents rotation of the hub and limits side-to-side movement of the post, and thus side-to-side deflection of the hub pin.
