It seems that at minimum, a flying erase head would be needed (most consumer video uses a full width erase head ahead of the flying (spinning) read/write heads; a flying erase head spins with the other heads, just a bit ahead, and can erase a track just before it is scanned). I was not aware that Sony made a home SuperBeta unit with this capability; some 8mm video units, including from Sony, have this feature (flying erase), though the quality of the recordings are not as good as Superbeta or even VHS HQ. There is also a VHS unit with jog/shuttle search (see Sony SLHF 750 & 900) and a flying erase head, unfortunately not sold in the US (consumer unit, but sold only in Japan). I think it is by Panasonic, not sure. I am sharing these few meager results of my own research - what I do not know yet is whether any of the flying erase head units can single-frame in record mode - it does not seem to be in the manuals, nor do salespeople even know what I mean. If it is possible, it probably requires some digital control, like an editing controller. I would love to know more, for the same purposes as the other posters. By the way, the Sony EVR-800, which is a home 8mm video deck, has a sound only mode (no video) which allows 6 digital soundtracks (each stereo). If used in slow speed (4 hrs/cassette) this would allow 24 hours of sound on one cassette (rewinding every 4 hours). (In video mode, you get one stereo digital soundtrack). Is this the "30 hr " format mentioned above, or does Sony have something new in Beta? -- Zhahai Stewart {hao | nbires}!gaia!zhahai
