    Abstract: A voice coil driven positioner is provided for positioning the magnetic head of a tape drive relative to the tape of a removable tape cartridge. The head positioner includes a low-mass carriage that supports the head on one end and the voice coil on an opposed second end. A low friction guide mechanism guides the carriage along a precision movement path that carries the head across tracks of a supplied multi-track tape and simultaneously carries the voice coil through a flux field generated by a stator. A movable portion of a position detector is attached to the carriage and located within the hollow of the voice coil for reciprocating into a hollow passageway of the stator together with reciprocation of the voice coil into another hollow of the stator. A fixed portion of the position detector is attached to the stator and located compactly within the hollow passageway of the stator. A programmable lookup table converts measurement signals output by the position detector into pre-calibrated, head-position indicating signals. A platform is provided on the carriage for mounting an interferometer prism used during calibration.

    Abstract: A magnetic recording tape (140) has recorded at at least one end of each of a plurality of longitudinal tracks (24, 60) therealong at least one frame (70, 72) of digitally encoded data representing the identity of each specific track. A recording/playback head assembly (12, 14, 16) is transversely positioned with respect to a longitudinal transport path along which the tape may be moved. The transverse position of the recording/playback head assembly may be monitored in response to the track identification data, to ensure positioning of the head assembly at a desired track (24, 60), to prevent recording onto an incorrect track, and to prevent playing back data from an incorrect track.

    Abstract: The invention concerns a process for positioning a positioning unit (2), in which the current for the positioning unit drive (201) is controlled by continuous comparison of the instantaneous position (xa) of the positioning unit as measured value with the target position (xn) as theoretical value, using a theoretical curve of the distance between start and target track. The theoretical curve is drawn, taking into account the back-emf of the drive unit, as a time-optimal step function. Sample values (ik and xk) corresponding to points on this theoretical curve are fed continuously at predetermined sampling intervals ( DELTA ) to an FIR filter (e.g. 52). Their filter coefficients (c0... cn) are chosen so that the points of inflexion of the theoretical curve are preferably cos-curve-shaped. The sampled values (ink and xnk) filtered in this way are converted into a control signal (is(t)) for the positioned unit drive. This process is carried out in real time, preferably by a signal processor.

    Abstract translation: 本发明涉及一种用于定位定位单元（2）的方法，其中定位单元驱动器（201）的电流通过将定位单元的瞬时位置（xa）作为测量值与目标位置（ xn）作为理论值，使用起始和目标轨迹之间的距离的理论曲线。 考虑到驱动单元的反电动势，绘制了理论曲线，作为时间优化的阶跃函数。 对应于该理论曲线上的点的采样值（ik和xk）以预定采样间隔（DELTA）连续馈送到FIR滤波器（例如52）。 选择它们的滤波器系数（c0 ... cn），使得理论曲线的拐点优选为cos-curve-shaped。 以这种方式滤波的采样值（墨水和xnk）转换为定位单位驱动器的控制信号（is（t））。 这个过程最好是由信号处理器实时进行。
