With the capacity to hold up to 3.9 TB of information, this is a disc that is not to be fooled around with.Current optical storage saves one bit per pulse, and the HVD alliance hopes to improve this efficiency with capabilities of around 60,000 bits per pulse in an inverted, truncated cone shape that has a 200 micrometer diameter at the bottom and a 500 micrometer diameter at the top. High densities are possible by moving these closer on the tracks: 100 GB at 18 micrometers separation, 200 GB at 13 micrometers, 500 GB at 8 micrometers and a demonstrated maximum of 3.9 TB for 3 micrometer separation on a 12 cm disc.At 15 meter resolution and 32-bit color (about the resolution found in unpopulated areas on Google Earth), a map of the land masses of Earth would occupy just over 2 TB. Using MPEG4 ASP encoding, a 3.9 TB HVD could hold between 4,600–11,900 hours of video—just over one year of uninterrupted video at usual encoding rates. Using typical satellite radio encoding (CT-aacPlus at 40 kbps), a 3.9 TB HVD could hold over 26.5 years of uninterrupted stereo audio.The transfer rate is at an average of 1 gigabit/second, or 128 megabytes/second, around 6 times the transfer rate for current 16x DVD storage.
he has eyebrows of authority + 5. Are you kidding?
Holy **** thats alot of music! and alot of space
