ABSTRACT:
A magnetic image recording system in which an image is electrically scanned to obtain a video signal and this is magnetically recorded on a magnetic recording medium. According to improvements of the present invention, for the image scanning means, use is made of a two-dimensional arrangement of a plurality of photo-sensitive elements and further of a self-scanning type solid-state image sensing device constructed so as to be capable of simultaneously reading out image scanning signals from the individual lines of the two-dimensional arrangement. With this solid-state image sensing device, in scanning an image, it is, for example, the individual odd number lines in the aforesaid two-dimensional arrangement that at first produce image scanning signals based on which the video signal is obtained. Then the video signal is recorded as an odd number field signal on the recording medium through a multi-head. Then, another video signal obtained by image scanning signals from the individual even number field signal is recorded on the recording medium through the multi-head. Compared with conventional systems in which horizontal field lines are sequentially scanned and recorded, all of the horizontal video scan line signals which constitute an entire field are simultaneously recorded in the present system. In other words, in contrast to conventional systems wherein images are recorded and played back at a rate of, for example, 60 fields per second, the system of the present invention enables a substantially greater number of fields to be recorded each second so that when the recorded fields are played back at a conventional rate, i.e., 60 fields per second, a substantial "slow motion" reproduction can be obtained.
