Abstract: PURPOSE:To stop a tape at an aimed stopping position with high accuracy by generating positional signals indicating the position of the tape among control signals on the basis of frequency signals from a frequency generator. CONSTITUTION:The terminal voltage Ep of a capacitor 54 rises only by iO. T5/C every time the frequency signals 8FG of time width T5 are inputted to an input terminal 60. When the frequency signals 8FG are inputted only by the moving number of the distance tape corresponding to the pitches of control signals CTL, the terminal voltage Ep is changed into reference voltage Es, and the capacitor 54 is reset by a switch 53. When the control signals CTL are regenerated during movement, the capacitor 54 is clamped to voltage Ec. The terminal voltage Ep is outputted as the positional signals. When the positional signals Ep are turned into reference voltage EB, brake starting signals Bs are outputted.

Abstract: PURPOSE:To obtain a slow motion reproducing picture, by feeding magnetic tape intermittently by one track pitch, and making the switching of each head of the 1st and 2nd rotating head pairs according to the output signal of the 1st and 2nd control signal reproducing heads. CONSTITUTION:A head switching pulse A is inputted from a terminal 11, and an intermittent drive pulse (b) is formed via monostable multi-vibrators 12, 13. The pulse (b) is applied to a drive circuit 14, where a capstan motor 15 is driven intermittently. On the other hand, the pulse A is applied to a differentiation circuit 30 and applied to gates 28, 29 via an inverter. Gate pulses (h) and (i) are given to the gate circuits 28, 29 to form differentiation pulses (j) and (k). The pulses (j) and (k) are applied to a F/F32 to form head switching pulse (l). In case of slow playback mode, (m) is at high level, and the inversion (l) signal is applied to a selector switch 35 and the (l) signal is to the selector switch 38 respectively. When the (l) is at high level, the switch 38 is selected to H side and the switch 35 is to L side to select heads A and A'.

Abstract: PURPOSE:To ensure a slow-motion reproduction without any band noise, by obtaining the signals alternately from the main head and an auxiliary head in the stop mode through an intermittent sending of a magnetic tape and then obtaining the signals at a time from both heads. CONSTITUTION:In the mode of steal reproduction I and steal reproduction, the magnetic tape is sent intermittently to give an intermittent scan to the track A1 alternately by the head A (the 1st main head) and the head A' (auxiliary head). When a tape shift is started, the track A1 is scanned by the head A (II). Then the track B1 is scanned by the head B (the 2nd main head) in the next field. Furthermore the track A2 is scanned by the head A in the following field (IV). When the tape shift is over, the track A2 is scanned alternately by the heads A' and A to perform a steal reproduction. In such a way, a slow-motion picture can be obtained without noise band.

Abstract: PURPOSE:To control the stop position of a tape by using horizontal synchronous pulses in a reproduced signal still reproduction of VTR on rotary double-head system. CONSTITUTION:Recording tracks A2-A4, and B2-B4 are given an azimuth and recorded by two different heads. In still reproduction, head surfaces scan from the initial point of track A to the terminal point of adjacent track B and two heads reproduce signals at parts shown by dotted lines and slanting lines. When heads and recording tracks bear correct position relation, horizontal synchronous pulses Ph detected by two heads shown by D and E can be obtained and in vertical blanking intervals of alternate frames, jumping of 0.5H is caused. If heads and tapes are not positioned correctly, pulses shown by B and C are obtained the jumping of 0,5H is disordered. For the purpose, the disorder is detected and the tape position is controlled to obtain the above-mentioned correct position relation.

Abstract: PURPOSE:To prevent a user from failing to reproduce a recorded picture by automatically stopping recording or stopping recording by the user in response to an alarm at the time when drum phase servo is off and cannot be followed by a servo circuit. CONSTITUTION:A signal CT and a signal SF are supplied to a microcomputer 30, and the phase difference between both signals is detected by a phase difference detecting process 31. A servo off duration discriminating process 32 discriminates whether the absence of the fall of the signal SF is continued for a prescribed time or longer in the width of period OK or not; and if it is discriminated that the servo off state is continued for the prescribed time or longer, the recording mode state is released and tape running is stopped and shut off by the discrimination output, or an alarm tone is emitted or an alarm lamp is lit. Thus, the state that reproduced pictures cannot be obtained at all is prevented.

Abstract: PURPOSE:To obtain inexpensively a picture with high picture quality by using an erasure head switchingly in response to the tape running speed to as to very a recording track width. CONSTITUTION:Recording heads 4, 5 are provided to a rotary head drum 3 at every 180 deg. to form a 2-head type and a recording signal is fed to each recording head. In this case, the gap Hw of the recording heads 4, 5 is selected the same width as a track pitch 60mum of the normal speed mode and the guard bandless recording is applied without overlapped recording. In this case, the gap width Ew of erasure heads 6, 7 is selected as e.g., 70mum and the height (x) to the recording head is selected as x=Tptheta deg..Tp/180 deg.. In applying recording by the double speed mode, a recording signal is fed to the recording head and an erasure signal is fed to the erasure head so as to apply the guard handless recording with track width Tp=Hw/2 on a magnetic tape 1 without overlapped recording.
