I am interested in recording short video sequences (2-10 minutes) for later retrieval on demand, which means, of course, that whatever technology I use needs some kind of accurate registration system. I'd like to be able to store several hours of material if possible. In addition, the recorder/player must be remotely controllable via an rs232 port. The obvious choice (to a video novice like me, anyway) is some sort of videodisc system. Since Write-Many-Read-Many technology has been promised for years but has yet to make it out of anyone's lab, it looks like some sort of WORM technology is the answer. I have a spec sheet for Panasonic's TQ-3031F optical disc recorder which promises up to an hour of motion video on 2 sides of a 12 inch disc with information retrievable on track boundaries. Estimated cost is $18K for a recorder/player and $3-4K for a player only. To store hours of material I would need a recorder/player and at least another player, possibly 2. I would also have to migrate discs as they fill up. I have been told by a dealer's rep (an admittedly biased source) that the Panasonic unit is the only one which meets my needs. I have also heard that Beta VCR might offer accurate enough registration for my purpose with, of course, greatly increased access time. However, for substantially reduced cost I could live with slow retrieval. My questions (finally): Is the Panasonic unit the only choice for what I want? Is beta a realistic alternative? Are there any other alternatives? As I said, I am a video novice looking for information. Any help would be appreciated.

I have a spec sheet Not true you can get 5 1/4 inch erasable optical now from at least 2 manufacters. Though data transfer rate would be a problem for real time video. >for Panasonic's TQ-3031F optical disc recorder which promises up to an >hour of motion video on 2 sides of a 12 inch disc with information >retrievable on track boundaries.

McDonnell-Douglas make a write-once system called 'Laserfilm'. The media is flexible 12" photographic material, and apparently low cost. I seem to remember a system by Teac/Tascam (or perhaps Toshiba) that also did write-once video. However, few of these systems are compatible with each other. -- {utzoo|mnetor}!dciem!zorac!dretor!king or king%dretor@zorac.dciem.dnd.ca Stephen J King =-= DCIEM Human Factors Division =-= (416) 635-2149
