摘要： A master tape (10) moves between first supply (16) and take-up (18) reels over a pinch roller. A slave tape (12) moves between second supply (22) and take-up reels (24) over a capstan (123). First and second guides are respectively constructed and positioned to regulate the movement of the master and slave tapes to aligned positions on the pinch roller (100) and the capstan (123). A heater between the pinch roller and the second guide heats essentially only a thermomagnetic layer on the slave tape to at least the Curie temperature. The heater (172) is adjustably positioned to facilitate the movement of the slave tape to the aligned position on the capstan. Brake shoes (46,151) respectively between the first guide (80) and the first supply reel (16), and between the second guide (154) and the second supply reel (22), control master and slave tape tensions and damp any variations in tensions. The pinch roller (100) is movable to a first position, locked in position relative to the capstan (123), to abut the capstan and facilitate the transfer of magnetic information from the master tape to the slave tape. In this disposition, the pinch roller locks the heater (172) in a fixed position relative to the capstan. The pinch roller and the associated guide are movable to a second position displaced from the capstan to facilitate the disposition of the master tape on the pinch roller. The heater is pivotable relative to the capstan to facilitate the disposition of the slave tape on the capstan. The rotational axis of the capstan (123), preferably of a unitary construction, is fixed.
摘要翻译：主带（10）在夹送辊上在第一供给装置（16）和卷取（18）卷轴之间移动。从动带（12）在第二供应装置（22）和卷取卷轴（24）之间在主导轴（123）上移动。第一和第二引导件分别被构造和定位以调节主带和从带到夹送辊（100）和主导轴（123）上的对齐位置的移动。夹送辊和第二导轨之间的加热器基本上仅将从动带上的热磁层加热到至少居里温度。加热器（172）可调节地定位，以便于从动带移动到主导轴上的对准位置。分别位于第一导向件（80）和第一供带盘（16）之间以及第二导向件（154）和第二供带盘（22）之间的制动蹄（46,151）控制主带和从带张力并阻止任何变化紧张局势。压紧辊（100）可移动到相对于主导轴（123）锁定在位的第一位置，以抵靠主导轴并便于将磁信息从主带传送到从带。在这种配置中，压轮将加热器（172）锁定在相对于绞盘的固定位置。压紧辊和相关联的导向件可移动到从主导轴移位的第二位置，以便于主带在夹送辊上的布置。加热器可相对于绞盘枢转，以便于从动带在绞盘上的布置。主导轴（123）的旋转轴线，优选为整体结构的旋转轴线是固定的。

摘要： Slave cassettes each including a slave tape and having a peripheral groove are stacked in a first station. Gripping fingers movable into the grooves in the forward cassette and the next cassette grip the forward cassette. During the pivoting of the cassette to a second station, a cover on the cassette is pivoted to expose the slave tape. At the second station, threading arms are moved from retracted to extended positions. The cassette and the threading arms are then moved to a third station planar with a pinch roller which is displaced from the capstan. The threading arms are then retracted to dispose the slave tape on the capstan. With a master tape on the pinch roller, the pinch roller is moved to a position abutting the capstan. The pinch roller and capstan are then rotated to transfer the image on the master tape to the slave tape such that the image beginning is at the slave tape beginning. The threading arms are extended; the pinch roller is moved to the displaced position; the cassette and the threading arms are moved to the second station; and the threading arms are retracted to decouple the slave tape from the capstan. The cassette is then moved to a position where belts are coupled to the cassette and the gripping fingers are thereafter released from the cassette. The belts then move the cassette to the mouth of a fourth station. Pins are rotated to move the cassette into the fourth station.

摘要： A master tape (10) movable in a closed loop including a pinch roller transfers a mirror image to a slave tape (12) movable in a closed loop including a capstan. A thermomagnetic layer on the slave tape has a Curie temperature above which magnetic information is destroyed and below which magnetic information can be recorded on such layer. The thermomagnetic layer is heated above the Curie temperature and is accordingly lengthened by thermal expansion just before the slave tape reaches the capstan. A first guide (151) contiguous to the heater regulates the slave tape tension. A downstream portion of a peripheral surface, preferably defining a cylindrical segment, on the guide receives a pressurized fluid for sensing the tape tension in accordance with the tape width, distance from the cylinder axis, and the fluid pressure. An upstream portion of the peripheral surface receives a vacuum adjustable to vary the spacing between the slave tape (12) and the downstream portion. This regulates the tape tension. The master tape (10) is lengthened by a second guide (52) having the same construction as the first guide to compensate for the lengthening of the slave tape by the heater and the first guide, thereby producing a true mirror image on the slave tape after the slave tape has cooled to the ambient temperature. Each of the master tape and the slave tape has a particular product of the Youngs modulus, tape width and tape thickness to provide a controlled strain on the tape when the tension on the tape is regulated.

摘要翻译：在包括夹送辊的闭环中可移动的主带将镜像传送到可在包括绞盘的闭合回路中移动的从属带。从带上的热磁层具有居里温度，高于该温度的磁信息被破坏，并且在该层上方可以记录磁信息。热磁层被加热到高于居里温度，因此在从属带到达绞盘之前相应地通过热膨胀而延长。靠近加热器的第一个引导器调节从带的张力。在引导件上的圆周表面的优选限定圆柱形部分的下游部分接收加压流体，用于根据带宽度，与气缸轴线的距离和流体压力来感测带张力。外围表面的上游部分接收可调整的真空以改变从带和下游部分之间的间隔。这调节胶带张力。主带被具有与第一引导件相同结构的第二引导件延长，以补偿由加热器和第一引导件引起的从属带的延长，从而在从带之后在从带上冷却时产生真实的镜像到环境温度。主带和从带中的每一个具有杨氏模量，带宽和带厚度的特定产品，以在带上的张力被调节时在带上提供受控的应变。
