I received 5-6 of these media for testing purposes from the TY rep office in Greece. Have you seen them around before?
They are regular TYG02 media, but come with the indication 'For Master" and have a cool protective sheet on the burning side for protection from dust and scratches
My guess is that they are the best G02 media when it comes to quality checks and they just put the protective sheet and market them for mastering. The difference in quality if any should be obvious only in 16x burning speeds i guess.
Will do some scans tomorrow. The pics will follow (sorry for the bad quality)
That’s DVD-R TYG02 for Master
