Abstract: A speed servo control for a tape drive comprising a take up reel having tape wound therearound, the tape extending to a supply reel and wound therearound. A flutter roller is arranged to press said tape that extends between the take up reel and the supply reel to rotate with circulation of the tape. A first tachometer is connected to said take up reel to rotate therewith. A second tachometer is connected to the flutter roller to rotate therewith, the first and second tachometers connected to a servo system for controlling the speed of the take up reel drive motor according to the select speed of the tape. The second tachometer from the flutter roller normally controls the servo for controlling the take up reel speed. A mechanism is provided for ignoring a tachometer signal from the second tachometer and controlling using the first tachometer, until the tape is tensioned against the flutter roller after start up. The mechanism for ignoring is advantageously a third tachometer connected to the supply reel and a pulse detector sensing pulses from the third tachometer and signal connected to the switch such that when a certain number of tachometer pulses are sensed from the third tachometer, or a certain stable frequency of pulses is sensed from the third tachometer, the switch is switched from the first tachometer (take up reel) as input, to the second tachometer (flutter roller) as input to the servo system.

Abstract: A torque command supplied to a tape running unit for drawing out and driving a tape wound on a first reel is modulated by a torque modulator depending on a moment of inertia of the first reel, a winding radius of the tape wound on the first reel, a moment of inertia and a rotating radius of the tape running unit, which are detected by a parameter detector. The first motor is responsive to the modulated torque command for rotating the first reel, thereby keeping the tension of the tape constant.

Abstract: When a processor sets a current instruction value and a rotating direction of a motor, two analog instruction signals of a positive polarity and a negative polarity are obtained after completion of a D/A conversion, the analog instruction signal of the negative polarity is selected by an instruction in the CW direction, and the analog instruction signal of the positive polarity is selected by the instruction in the CCW direction. The analog instruction signal of the polarity selected is added to a motor current detection signal which was negatively fed back by an adding circuit, so that an analog deviation signal is derived. A pulse width modulating circuit section outputs a PWM pulse in the CW direction for the negative polarity of the analog deviation signal and outputs a PWM pulse in the CCW direction for the positive polarity. At the same time, a CW switching signal is outputted for the negative polarity of the analog deviation signal and a CCW direction switching signal is outputted for the positive polarity. By inverting a detection signal of current detecting resistors serially connected to the motor, a negative feedback is certainly performed.

Abstract: A translatable capstan/tachometer assembly for use, for example, in transporting a magnetic media in a data record/reproduce apparatus, includes a capstan rotatably coupled to a tachometer unit. The assembly is supported for movement from an initial, unthreaded media position within a threading cavity of a data cassette, to a threaded or locked working position. The media path is arranged so that moving the capstan/tachometer assembly into the threaded position causes the media to wrap around the capstan with a substantial wrap angle. In play, record, jog or variable speed operational modes, movement is provided between a motor/disc assembly and the capstan/tachometer assembly to rotatably drive the capstan. In a high speed shuttle mode, the motor/disc assembly is disengaged but the capstan/tachometer assembly remains in contact with the media, thereby still providing tape speed information via the integral tachometer unit.
