Abstract: PURPOSE:To allow fine speed control at the time of startup of a motor by providing a PWM circuit generating PWM pulses having a duty corresponding to the output from a PWM data selecting means. CONSTITUTION:A section for raising the speed of a capstan motor 1 to a reference level comprises a timing level controller 12, a level selector 13, a register group 14, and a data setting circuit 15, wherein the timing level controller 12 switches a switching circuit 7 forcibly to S side at a predetermined timing. On the other hand, outputs from the register group 14 are fed selectively to S side of the switching circuit 7 by switching the level selector 13 sequentially. The register group store PWM data D1-Dn for controlling the speed of the capstan motor 1 finely and the PWM data D1-Dn are set by the data setting circuit 15. Since a driving voltage of (n) levels is fed at the time of rising of the capstan motor 1, rotational speed reaches quickly to a reference level.

Abstract: PURPOSE:To restrain the generation of a disordered image during a vibration and to restrain a jitter at a standstill by a method wherein the loop gain of a servo system for a VTR is made high during the vibration and it is made low at a standstill. CONSTITUTION:A loop-gain control system 1 differentiates the output of an angular velocity sensor used to correct a hand shake and obtains an angular acceleration. The angular acceleration is compared with a threshold value by means of comparators 13 to 15. A result is detected by means of a decoder 16. Switches 17 to 20 are selected, and gains G1 to G4 are set. Thereby, even when a VTR is at a standstill or it is being vibrated, it is possible to set an optimum loop gain.

Abstract: PURPOSE:To excellently suppress black-and-white inversion at the same time by inputting the output signal of a band-pass filter to an FM demodulator through the 2nd limiter circuit which operates at a signal level lower than that of the 1st limiter circuit. CONSTITUTION:The output of a limiter circuit 2 is supplied to a high-pass filter 3 which attenuates a low frequency component. The signal from this high-pass filter 3 is further supplied to a low-pass filter 4 which attenuates a frequency component higher than the highest frequency of a carrier. Then, the signal from this low-pass filter 4 is supplied to an FM demodulator 6 through a hard limiter circuit 5 which operates at the signal level lower than that of the limiter circuit 2. For example, when a pulse signal shown in a figure A is led out of the high-pass filter 3, this Signal is supplied to the low-pass filter 4 and then the output signal has its zero-cross part expanded in pulse width from T to T' as shown in a figure B. Consequently, the demodulation limit of the FM demodulator is increased substantially and black-and-white inversion is suppressed.

Abstract: PURPOSE:To eliminate the counting disturbance of a tape counter by using a comparing means which compares the output of a linearization arithmetic means with the real time and correcting the variation of the cycle for the signal obtained by linearizing the revolution detecting signals of supply and take-up reels when a tape is driven at a fixed speed. CONSTITUTION:A linearization arithmetic means 5 linearizes the outputs of both sensors 3 and 4 are delivers a tape count pulse B of every second unit. The cycle of the pulse B has big variation owing to an error of equalization and is compared with the cycle of a real time pulse A given from a real time counter 8 through a comparing means 7. A corrected count pulse D having the compressed width of variation is obtained from a correcting means 6 despite the big variation of the cycle of the pulse B. The counting disturbance of a display device 9 is not recognized visually because the device 9 is driven by said corrected pulse D.

Abstract: PURPOSE:To enable sure and highly accurate measurement by measuring impedance or admittance of a magnetic head in the state of opened magnetic gap and in the state of short-circuited by placing a magnetic body of high permeability, and executing measurement of reproduction efficiency from the two results of measurement. CONSTITUTION:Impedance or admittance of a magnetic head is measured beforehand with a magnetic gap (g) facing the contact face 2 with a magnetic medium opened magnetically. Then, a magnetic body 4 of high magnetic permeability is placed on the contact face 2 with the magnetic medium across the magnetic gap (g), and the magnetic gap is short-circuited magnetically and the second measurement is performed. Reproduction efficiency is found by calculating using commonly known calculating formula from the two results of measurement.
