Sony and Panasonic have joined forces to launch the successor to Blu-ray which they hope will grow the market for long-term, optical storage.
The launch of Archival Disc is the result of the manufacturers’ partnership to develop a standard for professional-use optical discs, which was announced in July last year.
Both firms now plan to launch systems with a recording capacity of 300GB per disc from summer 2015.
They also want to expand the recording capacity per disc to 1TB.
Disc specs:
| Disc size (type) | 300 GB (write-once) |
| Optical parameter | Wavelength λ=405 nm (nanometers), Numerical Aperture NA=0.85 |
| Disc structure | Double-sided Disc (3 layers/side), Land and Groove Format |
| Track pitch | 0.225μm (micrometers) |
| Data bit length | 79.5nm (nanometers) |
| Error correction method | Reed-Solomon Code |
