摘要： A tape drive system for tape play-back and/or recording devices is disclosed herein. The drive system comprises a first belt driven flywheel whose sole purpose is to control the rotary motion of a tape capstan. A second flywheel, which is also driven by the same belt that drives the first flywheel, is selectively coupled to a toothed pinion which is in constant meshing engagement with a toothed wheel rigidly connected to the collecting reel shaft of the play-back and/or recording device. For fast forward operation an idler pulley, which is directly driven by the same belt that drives the first and second flywheels, has a toothed surface coupled to the pinion while the pinion is decoupled from being driven by the second flywheel. For fast rewind operation, the toothed surface of the idler wheel is directly coupled to a mating toothed surface of a wheel rigidly connected to the supply reel shaft of the play-back and/or recording device while the second flywheel is again decoupled from the toothed pinion. The positioning of the idler wheel is controlled by movement of a T-shaped lever pivotally mounted at two points to the frame of the play-back and/or recording device.

摘要： Apparatus for transporting a web from a first reel to a second reel and cartridges for housing a web and distinct first and second web reels have a pair of distinct turntable structures for individually receiving, supporting and rotating the two reels. The turntable structures preferably are rotatably mounted on a base which may be the base portion of a web cartridge. In the latter case, the web cartridge has a cover complementing the base portion for housing the first and second reels when placed on the turntable structures.

摘要： A reel-to-reel web (tape) transport apparatus which has no tape length buffering between the supply and take-up reels. The tape follows a fixed length path from the supply reel, past a read/write head and guides, to a take-up reel. A two motor control mechanism is employed in which one motor drives the take-up reel and one motor drives the supply reel to maintain the appropriate tension and tape motion at the read/write head. The control mechanism is adaptive to dynamic changes as the tape is moved from the supply reel to the take-up reel. Three quantities are monitored: lineal tape position and the angular reel displacement of the supply and take-up reel. From these quantities reel radii are derived, tape inertia calculated and the velocity or position error is determined. A motor current algorithm is utilized to generate the appropriate torque for each reel to drive the control error to zero along a predetermined profile with negligible tape tension disturbances. The result is a reel-to-reel tape drive with static and dynamic performance characteristics which are independent of reel radius and inertia changes resulting from tape motion.
摘要翻译：卷轴卷筒纸（带）输送装置，其在供纸卷取卷轴之间没有带长度的缓冲。磁带遵循从供应卷轴经过读/写头并引导的固定长度路径到卷取卷轴。采用两个电动机控制机构，其中一个电动机驱动卷取卷轴，一个电动机驱动供带盘，以在读/写头保持适当的张力和带运动。当磁带从供带盘移动到卷带盘时，控制机构适应于动态变化。监测三个数量：线性带位置和供带盘和卷取卷轴的角卷轴位移。从这些数量得出卷轴半径，计算磁带惯性并确定速度或位置误差。利用马达电流算法为每个卷轴产生适当的扭矩，以便以可忽略的带张力扰动沿预定轮廓驱动控制误差为零。结果是具有静态和动态性能特征的卷轴到卷轴磁带驱动器，其独立于磁带运动引起的磁带盘半径和惯性变化。

摘要： A TAPE CONTAINER UNIT ENABLES STORAGE AND RETRIEVAL OF INFORMATION ON TAPE WITHOUT NECESSITATING REMOVAL OF THE TAPE FROM THE CONTAINER OR OTHERWISE FEEDING OR DRIVING THE TAPE PAST A PICKUP HEAD. THIS IS ACCOMPLISHED BY SUPPORTING THE TAPE IN FIXED RELATION WITHIN ITS CONTAINER SO THAT THE HEAD CANBE MOVED INTO CONTACT WITH THE TAPE SURFACE AND THE CONTAINER DRIVEN TO ADVANCE THE TAPE SURFACE ACROSS THE HEAD FOR RECORDING OR PLAYBACK OF INFORMATION ON THE TAPE. FURTHER THE HEAD CAN BE ACCURATELY POSITIONED AT ANY DESIRED LOCATION ON THE TAPE SURFACE TO PERMIT RANDOM ACCESS OF INFORMATION WITHOUT WINDING OR REWINDING THE TAPE.
