I hope so! There are a number of solid state memory recorders on the market but the capacities are still lower than I would desire and the price is still very high. The one big advantage to the solid state recorders from an extreme video point of view is that they will record at much higher "G" loads than can be relied on with a mechanical tape transport or a hard disk drive.
That is why these solid state systems are used in race cars, airplanes, helicopters and such.
Stack Ltd. Provide these systems harsh environment recording and we are looking into this type of system for our helicopters. Panasonic announced in their free video on the new P2 based camcorder that they will be providing much greater storage capacity and band width on thier P2 cards as the technology progresses. This is the type of memory card format used in the Stack Ltd. system. I would expect that from a reliability, size, weight, power requirements and performance standing this type of technology will begin to replace the hard disk recorders within the next 24 months (just my guess). http://www.stackltd.com/video.html
