摘要： A receiver/recorder for television transmissions whereby continuous recording of television transmission occurs from at least one channel onto a random-access rewritable recording medium. At each of a plurality of predetermined locations a binary code is periodically written to represent a filling of predetermined portions corresponding respectively to the predetermined locations. An indexing device responds to the binary code in order to automatically distinguish between a first in time recorded transmission on the medium from a second in time recorded transmission on the medium at a particular one of the predetermined locations.

摘要： A method of controlling the number of revolutions of a motor using the output of a tachogenerator, which determines the number of revolutions of the rotor, to regulate the motor. To improve the accuracy of such prior art regulating methods, which are limited by the mechanical tolerances of the tachogenerator elements, the actual time differences between pulses corresponding to respective fixed points on the rotor circumference during a revolution of the rotor are measured. The sequence of the pulses constituting the actual time differences is compared with a desired time difference sequence and a signal to control the driving motor is derived from this comparison.

摘要： The present invention relates to an optical recording medium having at least two information carrier layers, on which information can be written by means of a focused light beam. In this case, a separating layer is arranged between the information carrier layers and a respective transparent covering layer is arranged between the information carrier layer and the surface of the recording medium, the thickness of which covering layer substantially exceeds that of the information carrier layer. One object of the present invention is to propose an optical recording medium in the case of which it is possible to write to both information carrier layers using a low optical power. Further objects of the invention are to specify an apparatus and also a suitable method for writing to a recording medium of this type. A recording medium according to the invention has information carrier layers which are both semi-transparent.

摘要： A digital signal, such as obtained during playback from a DAT machine, includes a first component containing e.g. the audio content and a second component containing error recognition code. A signal processor derives in accordance with the second component an error signal representative of errors in the digital signal. A microcomputer then calculates an error rate signal. The error rate signal may be visually displayed or the error rate signal may be applied to the pre-amplifier circuits in the playback transducer stage to minimize the errors.

摘要： Several signal sources that produce corresponding digitally coded signals are coupled to a selection circuit. A microprocessor controls signal selection switches that select one of the signal sources in accordance with a priority schedule, provided that the signal source produces a signal at a frequency that is within a predetermined range of frequencies. The selected signal is then recorded in a tape recorder or forwarded to a signal reproducer device. To test whether a given signal source generates a signal at a frequency that is suitable for recording or reproducing purposes, the digitally coded signals from that source is coupled to an input of a phase-lock-loop circuit (PLL). When the signal causes a lock-in condition in the PLL, that signal source is then selected. If the lock-in condition does not occur, the test is applied to another signal source that is next in the priority schedule.

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 device for reading from and/or writing to optical recording media, including a beam generator, a focus device, which focuses the beam generated onto the optical recording medium at a focal point, a displacement device, which displaces the position of the focal point on the recording medium in accordance with a first direction of movement in dependence on an actuating signal, and a detector, which detects a beam reflected from the optical recording medium and outputs a regulating signal to a regulator. The regulator generates an actuating signal for the displacement device. The invention allows a higher data transfer rate to be achieved with an acceptable outlay. This is achieved by a beam influencing device arranged in the beam path and, in dependence on a further actuating signal of the regulator, influences the position of the focal point on the recording medium in accordance with the first direction of movement.
