摘要： A magnetic tape cartridge (11) is shown in which a length of magnetic tape (12) is wound on a reel hub (10) with the free end of the tape permanently connected to a generally rectangular-shaped leader block (13). The cartridge completely surrounds the reel of magnetic tape except for an opening (16) provided at one corner of the cartridge (11). This opening (16) permits tape (12) wound on the reel to be unwound as the leader block is moved away from the cartridge, preferably by an automatic threading mechanism. The cartridge comprises a leader block receiving well in which the leader block (13) is a snug fit. The walls (33, 51) of the well have the opening (16) in them through which the tape enters and leaves the cartridge. The walls (53, 33) of the leader block well are arranged to engage the leading and trailling walls of the leader block in a clamping relationship and help retain the block in the well in a position in which the opening (16) in the cartridge is substantially sealed by the leader block to prevent contamination from entering the cartridge when the cartridge is not in use. To remove the leader block from the well, it must initially be swivelled about boss (60) providing a mechanical advantage.
摘要翻译： 一个磁带盒（11），其中一段长度的磁带（12）被卷绕在一个卷轴轮毂（10）上，带的自由端永久地连接到一个大致矩形的引导块（13）上。 墨盒完全包围磁带卷轴，除了设置在墨盒（11）的一个角处的开口（16）。 优选地，通过自动穿线机构，该开口（16）允许卷绕在卷轴上的带（12）被解开，因为引导块被移动离开盒。 该盒包括一个引导块接收井，其中引导块（13）是紧密配合的。 井的壁（33,51）在其中具有开口（16），带通过该开口进入并离开料筒。 引导块井的壁（53,33）被布置成以夹紧关系接合引导块的引导壁和引导壁，并且有助于将块保持在井中在其中筒中的开口（16）的位置 被引导块基本上密封，以防止当盒不使用时污染物进入盒。 为了从井中移除引导块，它必须首先在凸台（60）周围转动，提供机械优点。

The walls (53, 33) of the leader block well are arranged to engage the leading and trailing surfaces of the leader block in a clamping relationship and help retain the block in the well in a position in which the opening (16) in the cartridge is substantially sealed by the leader block to prevent contamination from entering the cartridge when the cartridge is not in use.

摘要： A magnetic tape cartridge (11) comprises a device (16) settable to prevent inadvertent recording and thus erasure on the tape. The device (16) comprises a shaft (21) carrying a control disc (18) intermediate its length. The disc 18 either masks a sensor (23) from a light source (22) or allows illumination of the sensor according to its angular setting. The unit (16) is rotatably mounted in a sleeve (12) formed integrally with a part (11) of the cartridge. The unit (16) has a screwdriver slot (17c) and an indicator (17b). The sensor (23) is connected in a read/ write control circuit.

摘要： A magnetic head arm assembly comprises a lightweight, low inertia frustoconical arm (10) to which a magnetic head (12) is mounted at one end. The other end of the head arm is coupled to an end of a rotatable shaft (14), by which the arm can be pivoted. An electrical coil (16) which is disposed within a magnetic field supplied by permanent magnets (20,22) is fastened to the other end of the shaft (14). The pivotable magnetic head arm assembly may be vertically adjusted to control flying height and angularly adjusted relative to the surface of a magnetic diskto correct for azimuth variations.
