    摘要: A tape traveling apparatus drives differentially a tracking control actuator and a tension control actuator by inputting simultaneously into a tension controller a tracking instruction signal inputted into a tracking controller, and variably adjusts an amplification of the tracking instruction signal inputted into the tension controller according to an output of a tension sensor for detecting a tension variation of a tape, thereby eliminating a differential error between the tracking control actuator and the tension control actuator.

    摘要: A tracking system for a helical scanning type magnetic recording/reproducing apparatus which records and reproduces signals by a rotating magnetic head in which a tracking error signal is detected, and the feeding amount of the magnetic tape is controlled by a transfer section to accomplish tracking. The transfer of the magnetic tape is controlled so that the average transfer speed of the magnetic tape becomes a specified speed during a period when the rotating magnetic head does not reproduce signals. In particular, the tracking error signal is separated into low band and high band frequency components by a band separating circuit. A first transfer section is controlled by the low band frequency component to accomplish average tracking, and a second transfer section is controlled by the high band frequency component thereby changing the length of the magnetic tape between the rotating drum and the first transfer section. At the same time, while the rotating magnetic head does not reproduce signals, the second transfer section is controlled so that the tracking error signal becomes zero during the initial stage when the rotating magnetic head scans over the recorded track thereby to accomplish more stable tracking.

    摘要: A torque command is applied to a tape running unit. The tape running unit for draws out and drives a tape wound on a first reel and taken up on a second reel. The torque command is modulated by a torque modulator in accordance with a moment of inertia of the first reel, a winding radius of the tape wound on the first reel, a moment of inertia of the second reel and a rotating radius of the second reel, 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.
