摘要： PURPOSE: To stop a recording medium at an ideal position by detecting the phase coincidence between a periodic signal regarding a tracking error signal of a reproduction head and a recording track and a periodic signal regarding the tracing period of the head, then stopping the traveling of the medium.
CONSTITUTION: A magnetic tape 4 is wound around a rotary drum 6 and playback signals are obtained by heads 5a and 5b in normal reproduction or by heads 5a and 5c in still picture reproduction. An AFT signal generating circuit 15 generates a signal showing a tracking error continuously by using the playback signals of the heads 5a and 5b, and a drum PG13 showing the rotary phase of the drum 6 is obtained through a detector 12 and a generator 13. A capstan motor control circuit 8 ad a still reproduction control circuit 17 start operating simultaneously with a still reproduction instruction from a system controller 16. The circuit 17 detects the phase coincidence between periodic signals regarding outputs of the generators 13 and 15 and outputs the detection signal to the circuit 8 to stop the traveling of the tape 4. Thus, the tape 4 is stopped at the ideal position.

摘要： PURPOSE:To obtain a drive device for a motor capable of operating at both high and low speeds with the same supplied voltage always in high efficiency by using an inverter type drive system at the low speed time and using a unidirectional energization type drive system at the high speed time, thereby driving the motor. CONSTITUTION:Armature windings 1-3 are respectively energized by amplifiers 6, 7 which input rotor position detection signals from Hall elements HA-HC, and drive circuits A-C having transistors 4, 5 and a switch 8. When a transistor 11 of a drive circuit D is turned OFF and the switches 8 of the drive circuits A-C are closed, thereby driving the motor in the inverter type. On the other hand, the switches 8 are opened, the transistor 11 of the drive circuit D are turned from OFF to ON, thereby driving the motor in unidirectional energization type. The unidirectional energization type drive obtains high speed rotation as compared with the inverter type drive with the same supplied voltage, thereby operating at both high and low speeds.

摘要： PURPOSE:To improve the interchangeability of the titled device with other devices by detecting and compensating the position shift of a head which is produced in a record mode due to the secular change, etc. of a mobile member to which the head is attached and therefore positioning the head at a proper prescribed position at all times. CONSTITUTION:A larger quantity of light is irradiated to a phototransistor TRQ2 when the height of head is larger than the proper value, and therefore the voltage V1 is smaller than the voltage V2. Then V0=R3(V1-V2)/R2+VCT is satisfied, and V0 V2 is satisfied when the head height is smaller than the prescribed value, and at the same time V0>VCT is satisfied. Thus the bimorph plate is driven in the direction where the head height is increased. Therefore it is possible to keep the head at a prescribed level of height by a control circuit even though the bimorph plate has a deformation due to the secular change, etc. as far as the head height is once controlled accurately to its original state.
摘要翻译：目的：通过检测和补偿由于头部附着的移动构件的长期变化等而在记录模式下产生的头部的位置偏移，从而提高标题装置与其他装置的互换性，因此始终将头部定位在适当的规定位置。构成：当磁头高度大于适当值时，光量晶体管TRQ2会照射更多的光，因此电压V1小于电压V2。然后，满足V0 = R3（V1-V2）/ R2 + VCT，在V1 VCT时，V1> V2。因此，双压电晶片板在磁头高度增加的方向上被驱动。因此，尽管双压电晶片板由于长期变化等而具有变形，只要磁头高度一度被精确地控制到其初始状态，就可以通过控制电路将磁头保持在规定的高度。

摘要： PURPOSE: To eliminate influence upon the reproduction of a video signal and to obtain a tracking signal which is accurate to every reproduction speed by judging a frequency signal to be applied next on the basis of the playback output of a pilot signal recorded outside of a video signal area.
CONSTITUTION: A head 101B which is not used for the reproduction of the video signal is connected to a decision making circuit by a head changeover switch 102. The pilot signal at an overlap part is amplified by a regenerative amplifier 115 and an LPF116 extracts a reproduced pilot signal. While a head 101A(14) reproduces the latter half of a track, the head 101B(15) starts reproducing the overlap part. When multiplication by a frequency different from that of a track being reproduced at present is performed at the overlap part, f
1 and f
4 generate a 63kHz spectrum and f
2 and f
3 generate a 29kHz spectrum. Therefore, if a different signal is multiplied in the overlap state, the correct/incorrect signal of the multiplied signal is obtained synchronizing with head switching.

摘要翻译：目的：为了消除对视频信号的再现的影响，并且通过基于记录在视频外部的导频信号的重放输出来判断要再次应用的频率信号，获得对每个再现速度准确的跟踪信号信号区域。构成：不用于再现视频信号的头101B通过头转换开关102连接到判定电路。重叠部分的导频信号由再生放大器115放大，LPF116提取再现的导频信号。当头101A（14）再现轨道的后半部分时，磁头101B（15）开始重放重叠部分。当在重叠部分执行与当前正在再现的磁道的频率不同的频率的乘法时，f1和f4产生63kHz频谱，f2和f3产生29kHz频谱。因此，如果在重叠状态下将不同的信号相乘，则与头切换同步地获得乘法信号的正确/不正确的信号。

摘要： PURPOSE: To attain optimum tracking at the time of reproducing in a device writing data doubly on adjacent tracks by two heads with different head width each other by supplying pilot signals to the two heads to use the reproduced pilot signals and head width information.
CONSTITUTION: Reproducing is performed from the shown recording track as follows. When a reproducing video signal is inputted from a terminal 17, respective pilot signals f
1 Wf
4 are added to an adder 22. On the other hand, the output of a BPF18 is detected at its envelope and compared with reference voltage (e) by a comparator 24 to discriminates whether a signal f
1 is included in a recorded field or not. Consequently, the phase of a four-phase pulse is reset every time when the signal f
1 is reproduced. Namely, a signal having always the same frequency as that of a pilot signal of a reproducing track reproducing a video signal is applied to a frequency converter 27 as a local signal and frequency components of 10kHz and 30kHz are extracted from the frequency-converted signal by BPFs 28, 29 and detected by envelope detecting circuits 30, 31. Output signals from the circuits 30, 31 are supplied to a control signal generating circuit 32, which outputs an autotracking controlling signal.

摘要： PURPOSE: To simplify the circuit of a device by controlling the relative positions of a head and a recording medium by signals reproduced from one track and adjacent tracks and control signals obtained from a generating means in order different from that in recording.
CONSTITUTION: AND Circuits 44W47 output high-level signals during reproduction in the order of 44, 47, 46, 45, 44, 47W different from that in recording. Switches 35W38, therefore, turn on in the corresponding order and a switching signal whose frequency is switched in the order of 102, 148, 165, 119, and 102kHz is supplied to an LPF50. control signals are separated by an LPF14 from playback signals of heads 55 and 56 and multiplied by a multiplier 15 by a signal obtained from the LPF50. In this case, a spectrum generated by the crosstalk between a preceding and a trailing track is of 46 or 17kHz regardless of fields. When a tape speed deviates from a specific speed, the crosstalk between the preceding and trailing tracks is made different to produce a difference in generated spectrum. Therefore, the difference between the outputs of level detecting circuits 20 and 21 is supplied from a differential amplifier 29 to a capstan motor 26.

摘要： PURPOSE:To detect a running speed during reproduction being different from that during recording by providing a reproducing means which reproduces a video and a pilot signal and a detecting means which detects variations of the pilot signal and a playback output. CONSTITUTION:A tracking control signal from a demodulating circuit 12 is supplied to a capstan servo circuit and also led to BPFs 15 and 16 which allows only signals having a two-frame and a four-frame period to pass through them, and only their frequencies are extracted and detected by detectors 17 and 18 to obtain DC signals. Their detection output signals contain even simple noises, so they are averaged by integration circuits; only when the mean values exceed a preset threshold voltage E2, outputs A and B go up to a high level H. The H-level output A shows the standard speed reproduction of a tape recorded in long-time mode and the H-level output B indicates the long-time mode reproduction of a tape recorded in standard mode. The outputs A and B are inputted to a switching control circuit 27 to controls the tap running speed according to the outputs A and B.

H电平输出A显示长时间模式记录的磁带的标准速度再现以及H电平输出 B表示以标准模式记录的磁带的长时间模式再现。输出A和B被输入到开关控制电路27，以根据输出A和B来控制分接运行速度。

摘要： PURPOSE:To improve the sound and video quality at reproduction and to realize simply various reproducing technics, by recording various level control signals for the reproduction on one end of a tape of a VTR. CONSTITUTION:SWs 1, 2 are selected to the R position at the recording of a control signal. Frequency signals of oscillators 1, 2 are taken as fR, f1. A VR2 is connected to a mixer 14 to control the mixing ratio of FM and PCM audio tone. Thus, in giving a shift to a VR1 from the middle position, the level of f1 to a mix circuit 3 is changed and the ratio of the FM to the PCM of audio output is changed at the same time. The recording of a control signal is done by adjusting the said ratio with the VR1. The SWs 1, 2 are selected to the position P at the reproduction. The FR is extracted from the reproduced control signal at a BPF7 and the f1 is extracted at a BPF8, and they are detected and outputted to buffers 11, 12 as voltages VR, V1. When V1=VR is obtained, the same 1/2 VCC as the recording is given to a mixer 14 with an operational amplifier 13 even at the reproduction. Further, the mixed level of the FM, PCM audio at the recording of the control signal is obtained with R1=R2 even at the reproduction.

摘要： PURPOSE:To improve operability, by transmitting a high-speed operation signal to be kept by the first button operation, and by stopping the high-speed operation signal by the second button operation so that it becomes no need to keep pushing the operation button. CONSTITUTION:When high level at a D flip-flop DFF is generated by the first operation of a rapid traverse button, the reset of a counting circuit CC is released, and the circuit CC counts a clock pulse out of a clock oscillator. A Q- terminal of the OFF becomes on a high level and is locked at this state, and the generated output of an AND gate A1, namely rapid traverse controlling signal, is continuously kept. When a high level signal is supplied to a C-terminal of the DFF by button operation again, its Q-terminal changes to be on a low level. If the button is released, the output of the gate A1 changes to low level at the rising part of the DFF to stop the rapid traverse controlling signal.
