摘要： A track readjustment arrangement for a video magnetic tape recorder in which at least two magnetic heads travel across the direction of motion of the magnetic tape, for the purpose of scanning signals that are recorded on the tape. The magnetic heads are carried on a rotatable head wheel, and they have air gaps with an azimuth angle that alternates mirror-inverted around the central axis of the wheel. The phase errors that may occur in the signals scanned by the magnetic heads are from the horizontal sync pulses. The magnetic heads provide individually control parameters that are derived from the magnitude and direction of the phase errors. The head wheel is axially varied and reset as a function of the control parameters.

摘要： A brushless DC motor system includes a multi-pole DC motor having coils and permanent magnets. Optically scannable markers are applied on the circumference of a rotating member of the motor in fixed association with the magnets. By means of a scanner, these markers are converted to signals. These signals are evaluated with respect to their phase position and moment of commutation, and as a result commutation current is supplied to the coils.

摘要： A braking device for a tape player/recorder includes a pair of reel platters and a pair of pivotable brake arms individually supporting brake pads. A tension member biases the brake pads against the reel platters in a brake-applied position. The brake arms have extensions extending to a selected point. A spring biased pivotable lever arm includes a tracking end and an actuating end. The actuating end engages the brake arms at the selected point to bias the brake pads away from the reel platters against the action of the tension member in a brake-released position. A lifting element is coaxial with a motor driven shaft and includes a helical ramp extending around the lifting element and rising from a lower level to a higher level. An adjusting element is coaxial with the shaft and is outside of the lifting element. The adjusting element includes lower and higher faces respectively coincident with the lower and higher levels of the ramp. The adjusting element also biases the pivotable lever from the lower face to the helical ramp to enable the tracking end of the lever to rise from the lower level to the upper level and place the braking device into the brake-released position. A clutch disengages the adjusting element from the shaft in the brake-released position.

摘要： In an electronically commutated head drum motor in combination with a motor control circuit, commutation control and tacho signals are generated from the commutation of winding strands. One of the winding strands is used for the phase detection of the read/write heads arranged on the perimeter of the rotating head drum. A commutation signal is derived from the commutation of this winding strand and the commutation signal is set in relation to the reference signal of a signal track to be recorded or scanned.

摘要： A cassette loading facility has a guide frame arranged on a chassis in a fixed position. A receiving device is movable between a loading position, in which a cassette can be introduced and removed therefrom, and an operating position. The cassette is positioned on the chassis by means of positioning pins and catch apertures which are formed on the cassette housing. The catch apertures lock the cassette during its transportation between the loading and the operating position and also center it in the operating position. Instead of a fixed arrangement on the drive chassis, the positioning pins are fixed on a first pivoted lever which is pivotally mounted on the cassette receiving device and which can be pivoted into a first position in which the positioning pins release the cassette so that the cassette can be introduced into the cassette receiving device and removed therefrom, and can be pivoted into a second position in which the positioning pins engage with the catch apertures of the cassette whereby the pivoting of the first pivoted lever from the first position into the second position and vice versa is carried out at the loading position of the cassette receiving device. The cassette is locked in the cassette receiving device during its loading or unloading process by the positioning pins engaging with its catch apertures. Upon reaching the operating position, the lower ends of the positioning pins each engage with correspondingly arranged centering apertures in the chassis.

摘要： A system for adjusting the tension of a tape in a magnetic tape record/playback device includes a feed spool, a take-up spool and a motor for feeding the tape between the spools in a forward direction and a reverse direction. A tension sensor senses the tension in the tape as the tape is fed in the forward direction. The tension sensor is locked in its last existing position when the tape direction is changed from the forward direction to the reverse direction. A slip coupling applies a pre-adjusted tension to the tape when the tape is fed in the reverse direction.
