"Last year, Hitachi Global Storage Technologies predicted hard-drive companies would announce 1 terabyte drives by the end of 2006. Hitachi was only off by a few days."

CES: Hitachi Makes Video Storage Breakthrough
By Glen Dickson -- Broadcasting & Cable, 1/5/2007 5:51:00 PM
"Hitachi says it has developed a hard disk drive that can store a terabyte of data, a significant development for future digital set-tops with digital video recording capability. A terabyte could store about 125 hours of high-definition television using MPEG-2 compression at 18 megabits per second (Mbps) or almost 250 hours of HD programming using advanced MPEG-4 compression (at 9 Mbps)."

Though this is not stereographic (3-D) video, a single terabyte drive could store 10 days of MPEG-4 compressed high definition video. So you would need 36 terabytes to store a full year. So only 3,000 terabyes, 3 petabytes, to store 80 years of video.
This is well within the current rate of growth for hard drive storage to be reached in 20 years.
