  • Patent number: 4106063
    Abstract: In a circuit arrangement for a dropout detector for the detection of dropouts in signals which are reproduced from a record carrier, the signal path includes an amplitude discriminator before the threshold device which supplies a switching signal in the event of a dropout, the discriminator characteristic between two threshold levels of the output signals having a steep edge for amplitude discrimination in whose range the signal level which is decisive for the actuation of the threshold device is situated.

  • Patent number: 4005481
    Abstract: The invention relates to a recording and/or playback apparatus for video signals, equipped with a rotary head system with at least one recording and/or playback head and at least one erase head for the trackwise erasing of a video signal recorded in the video tracks, which tracks cross a further track, specifically a synchronization track, the erase signal being applied to the rotating erase head via a time-controlled gate circuit, which interrupts the path of the erase signal to the erase head while said head scans the further track, thus preventing a signal recorded in the further track from being erased.
