I am expecting to see the first shipment of Green Tune Audio CD-R for Mastering in another week or so .

From Mitsubishi:

""Green Tune" is a mastering disc that maximizes sound reproduction quality and meets every requirement for professional operations in the music studio....

To record and reproduce sound with the highest possible fidelity, "Green Tune" discs offer newly developed labels with green "silent coat"*1, AZO*2 recording layers and high-precision molding technology*3 which have a well-earned reputation for fidelity and reliability. These elements all work together to bring the new "Green Tune" CD-R discs to the level professionals demand....

As the DDP format^*4 penetrates further into the world of mastering, MKM will continue to develop "Green Tune" DVD-R that meets the exacting standards of music industry and respond to needs of customers. "

This disc is supposed to be the cream of the crop for audio mastering; we'll post complete information as soon as we receive it.   Interested in pro audio tape and drives?  Check out our selection...
