Abstract :
We have developed an organic write once media suitable for the DVR-Blue format. By use of organic material with high initial refractive index at 404 rim wavelength, a high density recording of 21 GB per 12 cm diameter single side disc was optimised to a practical level. Further optimisation of the recording pulse strategy and the media in near future promises the achievement of full compatibility with the DVR-Blue format.
