The basic question today is how to safeguard your video shots that are recorded on card/disk?
Sony may have the solution for you: http://pro.sony.com/bbsccms/ext/BroadcastandBusiness/minisites/NAB2012/product-Confidentia l-odsd55u.html
I wonder at what cost, though.
Jim, I have to agree with your thoughts, when you can get 2 TB hard disk drives for $120 (at today's high prices) it would be hard to see the usefullness of that cartridge that only holds 1.5 TB.
Unless they (plus the hardware Harm linked to) cost significantly less.
Which to me seems unlikely.
