摘要： The improved magnetic tape cartridge includes a leader block latch mechanism that includes an arm pivotally connected to the magnetic tape cartridge housing. A first end of the latch arm is accessible to the tape drive via an aperture in the magnetic tape cartridge housing and engagable with a feature on the leader block. The latch arm is normally in a first position where the first end of the latch arm engages a feature on the leader block to prevent its withdrawal from the magnetic tape cartridge housing. A spring biases the latch arm in the first position to maintain the leader block locked status as the preferred state. The tape drive uses a leader block latch release pin which enters the magnetic tape cartridge through an aperture in the housing to reposition the latch arm to a second position where the leader block is free to exit the magnetic tape cartridge housing.

摘要： The magnetic tape cartridge having a self docking leader block makes use of guide slots formed in the interior surface of the top and bottom plates of the cartridge housing, juxtaposed to the leader block opening in the housing, to mate with corresponding projections on the leader block. The guide slots are open at one end to capture the projections on the leader block and shaped to precisely guide the leader block along a predefined path into the opening.
摘要翻译：具有自对接引导块的磁带盒使用形成在盒壳体的顶板和底板的内表面中并与壳体中的引导块开口并置的引导槽，以与引导块上的相应突起配合。引导槽在一端打开以捕获引导块上的突起并成形为沿着预定义的路径将引导块精确地引导到开口中。

摘要： The improved magnetic tape cartridge includes a leader block retainer mechanism that provides a positive locking function to automatically secure the leader block in place in the opening of the magnetic tape cartridge housing. The leader block retainer mechanism comprises detent members springably attached to both the top and bottom sides of the housing, juxtaposed to the opening, to engage corresponding features on the leader block to resist withdrawal of the leader block from the housing.
摘要翻译：改进的磁带盒包括引导块保持器机构，其提供正锁定功能以将引导块自动固定在磁带盒壳体的开口中的适当位置。引导块保持机构包括可弹性地附接到壳体的顶侧和底侧的止动构件，与壳体并置，并与引导块相配合，以阻止引导块从壳体中退出。

摘要： The take-up reel is used in conjunction with a leader block that securely fastens the magnetic tape in the leader block such that the magnetic tape exits an aperture at one end of the leader block. The take-up reel accepts this leader block and completely seats it in an aperture contained in the take-up reel hub to ensure that no segment of the leader block protrudes from the take-up reel hub. The top and bottom plates of the take-up reel include guide slots to automatically position and align the leader block that is transported by the tape threading arm from the magnetic tape cartridge.
摘要翻译：收纸盘与引导块结合使用，该引导块将磁带牢固地固定在引导块中，使得磁带离开引导块一端的孔。卷取卷轴接收该引导块，并将其完全安置在卷绕卷轴毂中包含的孔中，以确保引导块的任何部分不会从卷带盘毂突出。卷取卷轴的顶板和底板包括引导槽，用于自动定位和对准由带穿线臂传送的引导块与磁带盒。

摘要： The improved leader block uses a substantially rectangular body that is equipped with two tape guide projections which form, in conjunction with the front of the body, a U-shaped channel open at one end and adapted to received the end of the magnetic tape that extends through the opening in the housing of the magnetic tape cartridge. The size and shape of this U-shaped channel substantially corresponds to the dimensions of the magnetic tape in order to precisely align the magnetic tape within the channel and with reference to the leader block body. The section of the front of the leader block body that constitutes the bottom of the U-shaped channel includes a plurality of parallel oriented, spaced apart grooves inscribed therein. These grooves extend from the top tape guide projection to the bottom tape guide projection in order to provide slots to receive corresponding projections that are included on the surface of the cover of the leader block. The cover fits into the U-shaped channel once the magnetic tape has been placed therein to sandwich the magnetic tape between the cover and the body of the leader block. The projections on the cover force the magnetic tape into the corresponding grooves in the face of the leader block body in order to thereby prevent the movement of the end of the magnetic tape with reference to the body of the leader block.
摘要翻译：改进的引导块使用基本上矩形的主体，其配备有两个带引导突起，其与主体的前部结合形成在一端开口并适于接收延伸的磁带的端部的U形通道通过磁带盒的外壳中的开口。该U形通道的尺寸和形状基本上对应于磁带的尺寸，以便将磁带精确地对准通道内的磁带并且参考引导块体。构成U形通道底部的引导块体的前部的部分包括内嵌在其中的多个平行取向的间隔开的凹槽。这些凹槽从顶部带引导件突出部延伸到底部带引导件突出部，以便提供狭缝以接收包括在引导块的盖的表面上的相应的突起。一旦磁带已经放置在其中以将磁带夹在封盖和引导块的主体之间，该盖适合于U形通道。盖上的突出部将磁带推入引导块体的表面中的相应凹槽中，从而防止磁带的端部相对于引导块体的移动。
