Abstract
To provide for reproduction of video signals from a magnetic recording tape in which the video signals have been recorded at a speed different from the reproduction speed, so that, upon passage of the tape about a reproducing drum, in a spiral path, the recording angle of the inclined tracks differs from the reproducing scan track (compare tracks 3-7 and 11, 12 of FIG. 1b), a further magnetic head is provided and so positioned that the signals which are not scanned by one head are, effectively, scanned by another head; by use of a programmed memory, the signals can be stored in proper sequence for reproduction as essentially complete TV signals, for read-out in accordance with a desired TV scanning standard, in analog or digital signal form.
