Abstract: A PCM signal recording and reproducing appa­ratus comprises first and second memory circuits (10, 11), in which PCM signals are read and written using the first memory circuit (10), while PCM signals stored in the second memory circuit (11) are error-corrected. At the end of writing by the first memory circuit, the first and second memory circuits are interchanged to read the error-corrected PCM signals stored in the second memory circuit. The read-out error-corrected PCM signals are then recorded on another magnetic tape (2).

Abstract: A conventional video recorder has a top plate 2 mounting a tape supply spool 22 and tape take-up spool 22a upon a common shaft 19. A recording assembly 6 has a conventional video recording drum and combines with a master cassette holder 4 to complete a cassette recording station. A roller system guides the tape from the supply spool 22 through the recording station to the take-up spool 22a. Stepper motors 3 provide rim drive to the the spools 22 and 22a and vacuum troughs 8 and 9 and associated photoelectric devices provide for speed control of the tape transport functions as a whole to ensure that tape is conveyed at a uniform speed without slack.

Abstract: Video and other information is provided on a first recording medium recorded at a standard speed and in a standard format in a series of tracks slanted relative to a direction of movement of the first recording medium. That information is reproduced from that series of tracks on the first recording medium in the form of electric signals seriatim at increased speed on the order of a multiple (n) of said standard speed, and such reproduced information is simultaneously rerecorded from said electric signals seriatim in a standard format with series of tracks on several second recording media at said increased speed, for replay of said rerecorded information by several end users at different times from said several recording media at standard speed.

Abstract: A signal copy device for a digital record/reproduction system includes an encoding circuit (12) for producing a first digital encoded signal corresponding to an analog audio signal. The encoding circuit (12) is connected to a first VTR (24) through a switch section (16) of a switch circuit (18) and : a first digital signal processor (22). A second VTR (64) reproduces and generates a digital encoded audio signal to be copied. The switch circuit (18) is connected to the encoding circuit (12) and the second VTR (64). The switch circuit (18) includes two switch sections (16, 28) which operate in cooperation with each other. When a reproduction signal is generated from the second VTR (64), the two switch sections (16, 28) are switched. The reproduction signal is supplied to the first VTR (24) through these switch sections (16, 28), thus accomplishing copying.

Abstract: A master tape (10) moves from a first supply reel (16) to a first take-up reel (18) in a first cassette (21). A slave tape (12) moves from second supply (22) to a second take-up reel (24) in a second cassette (28). A pinch roller (54) locked in a first position between the first supply and take-up reels abuts a capstan (92) between the second supply and take-up reels to transfer to the slave tape the image on the master tape. After such transfer, a signal sensing the end of the slave tape causes the pinch roller to be unlocked and to be moved to a second position displaced from the first position. In this position, the second cassette is replaceable by another cassette for an image transfer from the master tape. The rotations of the supply reel produce eccentricities (50) which vary tape tension. These tension variations are compensated at positions before the nip roller and the capstan by springs (44) guiding the tapes and by damping members (64, 66) attached to the springs. The damping members are prestressed to provide damped compliances in accordance with the tension variations. Stiffeners (70) are attached to the spring ends. The capstan (188) may be hollow and non-magnetic to receive a magnetic head (192). A constant amplitude alternating signal (198) applied to the head erases any image on the slave tape by providing a magnetic field greater than the coercivity of the slave tape but less than the coercivity of the master tape. Thus, the image on the master tape is transferred to the slave tape by abutting tape relationship.

Abstract: An electrical device includes an electrical element (12); a container (10) housing the electrical element; a rigid electrical terminal (22) extending through a hole in a wall (20) of the container; a bridge (40) between the wall and the element, the bridge having an opening (44) offset from an axis lying normal to the wall at the hole and the opening being aligned with a portion of the terminal; and an electrical connection made between the element and the terminal via the bridge opening, the connection being configured so that bulging of the wall causes the connection to break. Preferably, the container is a capacitor, and the electrical connection between the element and the terminal includes multiple separation points.

Abstract: In conventional copying processes, signals recorded in addition to the actual useful information, e.g. control signals for the synchronisation of recording-head switchover impulses, are not copied. Additional information can, however, be encoded in a variation of these signals, and this information is thus also not copied. In the invention, digital information recorded on the control track and detected by a reproduction device is transmitted by a transmission stage to a recording device where it is recorded again in digitally encoded form in an appropriate time gate on the control track. The process and device are of use in the copying of magnetic tapes containing address or index marks.

Abstract: A method and apparatus for reproducing magnetic recordings of digital data information particularly on flexible plastics discs known as ''Floppy'' discs. Data information is copied from one disc to another regardless of the encoding of information and the format of the disc without data corruption upon track changing by the recording transducer, it being unnecessary for the copier to react in any way to the data information in order to identify the buffer zones at which track changing must take place.

Abstract: This method produces, using a contact magnetic duplication process, a tape (10) having a plurality of recorded segments and separated by cue tones having a reduced tendency to generate false cue tones. The method includes applying a layer of a liquid dispersion to a nonmagnetic substrate. The method also includes the steps of orienting the pigment by applying a magnetic field (50), solidifying the layer of liquid dispersion on the substrate, and applying a demagnetizing field (52) to the layer to neutralize the remanent magnetization.

Abstract: Slave cassettes each including a slave tape and having a peripheral groove are stacked in a first station. Gripping fingers movable into the grooves in the forward cassette and the next cassette grip the forward cassette. During the pivoting of the cassette to a second station, a cover on the cassette is pivoted to expose the slave tape. At the second station, threading arms are moved from retracted to extended positions. The cassette and the threading arms are then moved to a third station planar with a pinch roller which is displaced from the capstan. The threading arms are then retracted to dispose the slave tape on the capstan. With a master tape on the pinch roller, the pinch roller is moved to a position abutting the capstan. The pinch roller and capstan are then rotated to transfer the image on the master tape to the slave tape such that the image beginning is at the slave tape beginning. The threading arms are extended; the pinch roller is moved to the displaced position; the cassette and the threading arms are moved to the second station; and the threading arms are retracted to decouple the slave tape from the capstan. The cassette is then moved to a position where belts are coupled to the cassette and the gripping fingers are thereafter released from the cassette. The belts then move the cassette to the mouth of a fourth station. Pins are rotated to move the cassette into the fourth station.
