Genuine very high quality product made by Panasonic.
Panasonic are one of the very few remaining companies that actually manufacture their own blank Blu-ray media. These are of the highest quality & result in consistently excellent burned discs. I've used many other brands & Panasonic media is about the best you will find anywhere.
Price per disc is actually very reasonable compared to other brands particularly when you get excellent burn quality & zero coasters.
Disappointed in the recording quality of these discs
I may have gotten a bad batch of discs. When comparing the recording quality of this version of BD-R (1-6x, RA1 media) to the older version (1-4x, T0-1 and T0-2 media) the difference is astounding. The older version is much better, clearer, more defined, and the sound quality differs immensely. The older version, 1-4x, is much harder to find and costs twice as much. I am UNCERTAIN about this assessment, but my research has told me that Panasonic has changed their reflective dyes (the 1-6x, RA1 media) and that the newer dyes are the low-to-high (LTH) version reflective dyes. The older version, 1-4x, T0-1 media) is definitely the high-to-low (HTL) version of reflective dyes, and most critical recordists know that the difference is great between the two. LTH is undesirable, cheaper, and produces less quality results, and the archival times for the LTH is much less. I will NEVER purchase another spindle of these 1-6x discs.
Not cheap but the only Japanese made media left on the market....they have always worked very well. These are shipped direct from Japan. Top quality (so far)
