    摘要: A cassette tape-loading apparatus applied to a magnetic recording and reproducing apparatus using a cassette tape comprises a device for determining the amount of rotation of supply and take-up reels, a device for detecting the rotational direction of the reels, and a device for detecting the amount of tape drawn out of the cassette. Before loading the cassette tape, the ratio of winding diameter between the supply and take-up reels is computed, and the result is used to set the torque of the reel-driving motors and start the loading operation. At the time of loading, on the other hand, the amount of rotation of the two reels is determined, and the winding diameters of the reels computed from the winding diameter ratio and the amount of drawn-out tape thereby to set a proper tension of the magnetic tape. Since the tension applied to the magnetic tape and the torques of the reel motors are set in accordance with the winding diameter ratio and the winding diameters, magnetic tape of substantially equal amount is drawn out of each of the two reels, with the result that the magnetic tape is not subjected to an abnormal tension, thereby making possible a stable cassette tape-loading operation without damaging the tape or displacing the tape position.

    摘要: The precedingly reproduction signal reproduced by a precedingly reproducing head is recorded on a tape. If it is detected that the reproduction signal includes abnormality owing to a reason such as poor error rate, the recording operation is stopped. Then, for retrial of the recording, the information on the position where the abnormality has occurred is held. A memory may be provided to always rewrite and store the signal reproduced by the precedingly reproducing head, and also a simultaneously reproducing head which is different from the precedingly reproducing head may be provided to immediately monitor the recording state of the signal recorded on the tape. If it is detected that the signal reproduced by the simultaneously reproducing head includes abnormality, the recording operation is stopped, the information on the position where the abnormality has occurred is held. Further, the rewrite operation in the memory is stopped and the original precedingly reproduction signal corresponding to the signal to be recorded at the position where the abnormality has occurred is held in the memory.

    摘要: A magnetic recording and reproducing apparatus having a construction in which a digital signal including index signals recorded on a magnetic tape is reproduced and rotary magnetic heads are movable. The digital signal is reproduced by digital signal reproducing means including the rotary magnetic heads. A particular index signal among the index signals is detected by index signal detecting means. Further, the timing for reproducing the particular index signal is detected by timing detecting means. The rotary magnetic heads are moved and deviated in the direction of the rotary shaft of the rotary cylinder by rotary magnetic head position deviating means. Tape speed detecting means compares a reproduction clock with a reference clock and outputs a tape speed signal. First rotary magnetic head position deviation control means forms a control input for the rotary magnetic head position deviating means on the basis of the tape speed signal. Second rotary magnetic head position deviation control means forms the control input for the rotary magnetic head position deviating means on the basis of an output signal of the timing detecting means.

The tracking control system includes: an apparatus, attached to the rotary cylinder, for moving the magnetic heads in the width direction of the tracks in accordance with a tracking signal; and an apparatus for sampling the signals detected by the magnetic heads, for comparing a preceding sampled value with a present sampled value, and for generating the tracking signal such that the present sampled value is larger than the preceding sampled value. The tape tension control system includes: an apparatus for detecting changes per predetermined time in levels of the signals detected by the magnetic head; an apparatus for giving a tension to the moving magnetic tape and for adjusting the tension in accordance with a tension control signal; and an apparatus for generating the tension control signal to adjust the tension according to change amounts per predetermined time of the signal levels to a reference value. Further, the switching apparatus includes switching means for receiving the signals detected by the magnetic heads and for selectively energizing either one of the tracking control system and the tape tension control system in accordance with the levels of the signals. Another magnetic recording signal reproducing apparatus according to the invention comprises: two magnetic heads arranged to a cylinder so as to simultaneously trace adjacent tracks; an apparatus, attached to the cylinder, for individually moving the two magnetic heads in the width direction of the tracks in accordance with a head position control signal; and an apparatus for generating the head position control signal to move the magnetic heads in the width direction of the tracks in a manner such that when the recorded signals are reproduced at a speed different from a tape moving speed upon recording, amplitude levels of the reproduction signals detected by the two magnetic heads locating at predetermined track positions have a relation of opposite phases.
