Hitachi demonstrates playback of Quadruple Layer Blu-ray Disc using "normal drive"
- Demonstration is playing a QL Blu-ray disc, switching layer and showing its signal pattern by an oscilloscope
- Each layer has different frequency signal pattern (L0:3T, L1:4T, L2:5T, L3:6T) to distinguish easily current reading layer from other layers
- Reader is not a special made equipment, it is based on Hitachi's commercial BD drive GBW-H10N with modified firmware and some part of optics
All players can perhaps be updated via firmware. It is assumed that the discs themselves can contain the firmware to install to any Blu-ray device, allowing the laser to read all 4 layers. And since Blu-ray has no lag between layer switches, video and audio will be seamless.
Western Media should be picking this article up soon.
I like. Imagines Star Wars movies on 200gb discs each.
EDIT: I mis-worded the title. I don't mean to assume that all player will play the disc, but that it's possible. <C'mon, it's 5am here> :lol
