HVD (Holographic Versatile Disc) and Future Knowledge Archiving
Floppy (1.44 MB), CD (700 MB), DVD (4.7 GB)
1 CD = 486 Floppy Disk
1 DVD = 6.7 CD
What’s next? HVD (Holographic Versatile Disc)
1 HVD (Holographic Versatile Disc) = 200 DVD = 1 TB = 300 Hrs Video
HDV stands for HVD，Holographic Versatile Disc, it is a technology of a plastic disk that can hold over 200 DVD quality movies and transmitting data at 1GB/sec. This technology is currently under development by six world home entertainment and IT leading companies such as Fuji Photoand, CMC Magnentics and Optware.
Imagine the technology being used in the education industry, one subject has total of 40 hours face to fact teaching/learning time per term. A student can literally tape record the entire semester (4-5 subjects) class room experience into ONE HVD! While I am still struggling what to throw out from the piles of valuable/invaluable college class notes, my future alumni can fit their entire undergraduate class notes (video shot straight from classes) into 5 plastic disks! With this technology, I believe video based knolwedge archiving will be come more reliable and afordable.
Comments:
Of course, with removable optical media that big, we'd need internal storage on our laptops in the order of 10TB... (comfort level is ~10 Big Optical Disks should fit on an average hard drive - my 60GB laptop drive can store ~10 DVDs...) Currently 10TB of storage is a wee bit spendy, but in a few years...
