摘要： A reel assembly apparatus for coaxial magnetic tape reels is provided in which both an inboard reel and an outboard reel may be reliably clamped to their respective drive spindles from the outboard side of the assembly apparatus with ease and convenience. For the purpose of clamping the inboard reel, an internal locking nut extends radially in the plane of the inboard reel from its drive spindle into threading engagement with a hub of the inboard reel. A linkage, extending axially through the outboard drive spindle, rotates in response to turning movement of a bail accessible to an operator. The locking nut, in response to the rotation of the linkage, (1) initially causes the inboard hub to rotate, relative to the inboard reel, a limited amount into a reel-clamping position, and (2) then causes an axial movement of the inboard hub. This latter movement drives the inboard reel axially, to clamp it against a radially extending member of the inboard drive spindle. A second locking nut, coupling a second bail to the outboard hub, serves similarly for clamping the outboard reel to its drive spindle. With the locking nuts in the planes of their respective reels, the reels can be positioned axially immediately adjacent each other, thereby conserving space for a compact design.
摘要翻译：提供了一种用于同轴磁带卷轴的卷轴组装装置，其中内侧卷轴和外侧卷轴可以方便和方便地从组装装置的外侧被可靠地夹紧到它们各自的驱动主轴上。为了夹紧内侧卷轴，内部锁定螺母在内侧卷轴的平面中从其驱动主轴径向延伸，与内侧卷轴的轮毂螺纹接合。轴向延伸穿过外侧驱动主轴的联动装置响应于操作者可接近的吊环的转动而旋转。锁定螺母响应于联动装置的旋转，（1）最初使内侧毂相对于内侧卷轴旋转有限的量进入卷轴夹紧位置，并且（2）然后使轴向运动内置集线器。后者的运动轴向驱动内侧卷轴，将其夹紧在内侧驱动轴的径向延伸部件上。第二个锁定螺母将第二个吊环连接到外侧轮毂，用于将外侧卷轴夹紧到其驱动主轴上。通过将锁紧螺母固定在它们各自的卷轴的平面中，卷轴可以轴向定位成彼此相邻，从而节省紧凑设计的空间。

摘要： Methods and apparatus for transferring information relative to a recording medium bend the medium about a first axis and move an information transfer stimulus in an arc over such bent medium about a second axis laterally offset from and extending at an angle to the first axis. These methods and apparatus impart to the bent medium a wave-shaped configuration for accommodating the mentioned arc in a perpendicular plane through the second axis. The wave-shaped configuration may be imparted to the medium with the aid of a guide or roller having a wave-shaped contour.

摘要： Tape guiding methods and apparatus advance a tape through an arcuate bend having equal radii at both edges. Within that bend an unbalance providing a net force transversely of the tape is created at the tape edges while maintaining the equal radii. The advancing tape is guided by applying it with the created net force to a reference surface while maintaining the equal radii.

摘要： A metallic mass is placed into frictional engagement with a transducer head structure. Vibrations of such transducer head structure are dampened by relative displacement between the metallic mass and frictionally engaged transducer head structure. Plastic deformation of the metallic mass frictionally engaging the transducer head structure may also be employed to dampen vibrations. The metallic mass may be pressed into frictional engagement with the transducer head structure, and vibrations from the frictionally engaged transducer head structure may be transmitted through the metallic mass to the viscoelastic polymeric layer to set up shearing strains in that layer causing the mass to dampen vibrations of the transducer head structure by lagging oscillation in frictional engagement with that transducer head structure.

摘要： A belt driven tape cartridge employs a pair of tape reels on fixed spaced axes within a cartridge case and on which a tape extending between them is convolutely wound to form tape rolls. Tape is transported between reels when the reels are driven by a taut belt that extends between the rolls and around a drive roller at one side of a line connecting the tape reel axes and around an idler roller at the other side of that line. The drive roller rotates on a fixed axis which in preferred form is equidistant from the two tape reel axes. The idler roller rotates on an axis that is parallel with the other axes but is free to move laterally.

摘要： Disclosed is a reel hub latch assembly used in magnetic tape recording/reproducing apparatus. The disclosed reel latch assembly accurately locates a reel on a hub and prevents slippage between the hub and reel when the reel is rotated to transport tape onto and off of the reel. The reel mounting hub has an annular groove containing an annular, U-shaped radial spring at the bottom of the groove. The radial spring has a plurality of circumferentially spaced fingers. An annular garter spring is located in the groove overlying the circumferentially spaced fingers of the radial spring. A magnetic tape reel, mounted on the hub, has a conical inner wall which is engaged by the garter spring. Preferably, the engaging portions of the spring are shaped to conform to the shape of the conical wall to reduce stresses on the reel.

摘要： A magnetic tape cassette transport/accessor assembly for use in a system including magnetic tape cassette storage and magnetic tape cassette record/reproduce apparatus. The cassette transport/accessor assembly transports cassettes between locations in the system in a gentle and reliable manner. The magnetic tape cassette transport/accessor assembly includes upper and lower carriages having spring-biased, V-grooved wheels, which travel on spaced, parallel, upper and lower V-shaped horizontal rails located at the top and bottom of the cassette storage and record/reproduce apparatus. An accessor platform travels on two vertical rails rigidly mounted on the upper and lower carriages. The accessor platform supports two accessor assemblies which travel laterally on lead screws to effect insertion and extraction of magnetic tape cassettes. The transport/accessor assembly is lightweight since no actuating motors or motor supports are mounted on it. Thus, the assembly is easy to remove and replace, requires minimal maintenance and has a long operating life.

摘要： Helical scan tape recorder/playback apparatus includes a pair of concave air-bearing surfaces disposed immediately adjacent and tangential to opposing sides of a circumferential surface of a rotary head scanner, to cooperatively form a path for guiding magnetic tape past the head scanner at a predetermined angle other than zero degrees. A vacuum source serves to evacuate air from the vicinity of each air-bearing surface to create an air pressure gradient the effect of which is to cause magnetic tape to ride on a thin film of air interposed between the tape and each air-bearing surface during transport of the tape from a supply reel to a take-up reel.

摘要： A hollow-cylindrical member, such as a reel, is releasably retained on a rotatable hub against forces tending to loosen the reel. To this end, a plurality of locking keys are inserted into corresponding axial slots in the reel at the inside thereof. These locking keys are first driven up corresponding ramps on the hub into engagement with the inside of the reel at corresponding slots. After such engagement, and during rotation of the hub and reel, the locking keys are continously biased or further urged into their corresponding slots in order to inhibit any looseness between the releasably retained reel and the rotating hub. By way of example, tape reels of large size and mass may thus be securely retained against strong inertial forces occasioned particularly during rapid reversals of the reel rotation as occurring, for instance, in modern instrumentation tape recording and data processing machines.
摘要翻译：诸如卷轴的中空圆柱形构件可抵抗倾向于松开卷轴的力而可释放地保持在可旋转的毂上。为此，将多个锁定键插入卷轴的内侧的对应的轴向槽中。这些锁定键首先被驱动到轮毂上的对应的斜面上，以在相应的槽处与卷轴的内部接合。在这种接合之后，并且在轮毂和卷轴的旋转期间，锁定键被连续地偏置或进一步推动到其相应的狭槽中，以便防止可释放地保持的卷轴和旋转轮毂之间的任何松动。例如，由于例如在现代仪器带记录和数据处理机中发生的卷轴旋转的快速反转，特别是在大的尺寸和质量的卷轴上可以被牢固地保持抵抗强烈的惯性力。
