So, in a post over in the bargain basement a month or two ago, the venerable Great Quality brand of DVD media that Fry's Electronics in the states sells came up in a discussion. Someone mentioned that the 16x media codes have been reported as being SONY16D1 or SONYD21, but I speculated that they were probably fake. ScoobieDoobie then countered that by saying we don't know for sure, because reports of how they burned for some people seemed to be similar to that of Sony. I said back to Scoobie that only the hub codes would tell us for sure.
Well, it seems that very few people have ever bothered to either look at the hub codes on GQ media, or the people who bought them weren't experienced enough to know what to look for, so we never got any confirmation on exactly who was making them. GQ media has such a bad reputation, mostly due to the old 4x and 8x media, that no one bothered to see if anything had changed with the 16x disks. The 4x and 8x media could be any kind of crap, with innumerable media codes, so people threw up their hands, and relegated it to the Princo and G05 dustbin.
So, I happened to be near a Fry's today, and decided to take a closer look. Turns out they were on sale ($6 for a 50-pack after rebate), so I grabbed a pack of -Rs. I haven't opened it just yet (that will come soon), but the first thing I noticed is that the batch codes are the same as genuine Sony disks. The top disk on my GQ pack reads:
The batch code on one of my genuine Sony-brand disks reads:
I also noticed that the cakebox looks eerily similar to the Sony MIT packages, including the same lock+open font on the top. All the packs I checked at the store looked the same, and had the same Sony-style codes.
So, as of this moment, I'm inclined to believe that current 16x GQ media is being made by either Daxon or Lead Data, and is somewhat equivalent to Sony MIT media.
