The new technology will provide orders of magnitude higher bit density for RFID tags as compared to "prior art" or other competitive approaches.
This process eliminates coating disturbances and orients the particles precisely to allow for maximum bit density and storage capacity.
As with other blue laser formats (and like HD-DVD), BD technology utilizes a shorter wavelength--405 nanometer blue violet laser--that, when combined with a higher numerical aperture and tighter track pitch, enables greatly improved bit density on the 120mm disc.
