摘要： A magnetic recording and reproducing apparatus for recording a desired sound or picture signal to a magnetic tape by a magnetic head. At the time of normal-speed recording and reproduction, the magnetic tape is taken up at a constant speed, but by changing the tape travelling speed of the tape on the rotary drum, DTF control and high-speed noiseless reproduction are enabled. The tension of the tape on the entrance side of the rotary drum is controlled to a desired value. This apparatus includes a tape tension actuator and a tape drawing actuator on the entrance side and on the exit side, respectively, of the rotary drum. In DTF control, both tape actuators correct a tracking error of the tape in cooperation with each other. In high-speed noiseless reproduction, both tape actuators are differentially driven so as to lower the tape travelling speed on the rotary drum. Both tape actuators are driven in feedback control using the modern control.

摘要： A magnetic recording and reproducing apparatus that realizes a DTF control in a wide frequency range and a noiseless high-speed replay at several tens of times the normal replay speed without degradation of picture quality. Optimum contact between the head of the apparatus and the tape is provided at all times by performing tension control with high precision and in a wide frequency range. A pair of supply side stationary pins and a supply side movable pin driven by a supply side tape actuator is provided on the magnetic tape supply side of the head cylinder that has a rotary head. By controlling the supply side tape actuator to move the movable pin, the tension of the magnetic tape at the head cylinder can be controlled by taking into account the acceleration of the deck. When the tape is replayed at a speed different from the recording speed, the supply side tape actuator and a takeup side tape actuator are operated differentially from each other to perform good tracking.

摘要： A magnetic recording and reproducing apparatus for performing automatic tracking in a video tape recorder of a helical scan type. A magnetic head is wobbled by an electromagnetically driven actuator in a transverse direction of a recording track, a tracking error signal is obtained by extracting a signal component attributable to this wobbling from a signal reproduced by the magnetic head, and the extracted signal component is fed back to the electromagnetically driven actuator. By setting the magnetic head width to 1-1.5 times the recording track width, a dead zone is made small, and the tracking error signal is obtained positively. In addition, by setting the frequency for driving the electromagnetically driven actuator at a level between a primary resonance frequency and a secondary resonance frequency and by subjecting the driving frequency to phase conversion, the driving frequency is converted into a high frequency to permit highly accurate tracking. Furthermore, any deviation in the tracking by a fixed magnetic head caused by a DC current and the like is prevented by extracting a low-frequency component containing a DC component from the tracking error signal and by feeding back that extracted signal to a capstan motor for driving a magnetic tape.

摘要： As a measure against vibration caused by disturbance due to mass eccentricity of a disc, a conventional disc device has a means to add an auxiliary mass that passively operates. This method has no way to enhance vibration damping effect other than setting the auxiliary mass to be large, and therefore there is a problem that the device becomes large. An auxiliary mass 300 is actively driven by an auxiliary mass driving portion 360. The driving of the auxiliary mass 300 is performed by amplifying a signal corresponding to a force transmitted from a main frame portion 100 to the auxiliary mass 300. This achieves a vibration damping effect using the small auxiliary mass 300 to the same degree as that where the large auxiliary mass is mounted.
