25GB TDK 4x BD-R, 25pk Spindle, Branded non-printable
Made in India
Lesson number one in optical media burning - learned the hard way by many who lost their precious data they thought safe - is to never believe that just because your favourite burning software says that a disc has been 'successfully burned', you actually have a good quality disc on your hands! This is far from being true, particularly nowadays when media quality is becoming a bit of a challenge, and even good brand names compromise on quality beyond acceptable limits. Unfortunately this media is one such example...
The only way of getting an accurate enough picture of how good a disc/burn actually is (at the consumer level / using consumer level tools), is to carry out a proper 'quality scan' using one of the BluRay drives capable of performing such scans (typically drives based on the Mediatek chipset which offer this capability). Those interested in such things can find lots of useful info at MyCE.
These TDK discs use a PHILIPR04 MID ... and they are of very poor quality. It is a pity that TDK have chosen not to use their own high quality TDKBLDRBB-000 MID and went instead for the cheaper and lower quality PHILIPR04 (Media ID). Unfortunately this choice of cheaper MID really shows. Some PHILIPR04 MID discs can be quite good (I had good experience with some KODAK branded 4x BD-R media in the past), but this new batch used by TDK are complete rubbish. They might as well be qualified as factory rejects which should go straight to the bin!
I've got several Blu-Ray burners and plenty of Blu-Ray burning experience, and I tested this media on all of them at both 4x and 2x (hoping for better quality).Read more ›
So, like I say although these figures are poor, the discs do work. If you're creating home movies or discs to transfer files then they're fine as they are readable. Creating for a back-up? Spend the money and get better discs.
Side note - This trend has followed throughout all of TDK's brands, including DVD's and CD's.
One thing to report, the packet said 135 mins in HD, which is just over 2 hrs of recording. But on my machine I get about 6 hrs of HD content, recording HD programs from TV on a 25GB disc. The program I recorded onto this first disc was over 4 hrs long, and came out perfectly. I was even able to give it menus, with a little movie on the side. Looking at the disc, I have nowhere near used the full capacity of this disc, so where 135 mins comes from makes no sense.
Contrary to other reviews I have found these TDK BD-R discs to be VERY reliable in my recorder, and having used about 25 of them so far I may have had 1 or 2 that have failed to burn correctly, I think these may have been because of finger prints or other marks on the disc that I had not cleaned off, as It seems to me that ALL Blu-Ray DISCS are more critical of surface debris than DVD's possibly because of the density of the data being written.
I have bought my previous discs from Maplins at £9.99 (50% off) but these are even better value. It does not matter to me where they are made as long as they are genuine TDK's, mine were manufactured in Taiwan, and the Imation connection is not a problem either as I have used there discs in my custom built computer systems for many years with no problems.
In conclusion these are great value for money discs, but like all disc recording Make Sure The Whole Surface Of The Disc Is Clean Before Writing To It, I use a Spectacle Cleaning Cloth for this, and only burn up to the maximum rate of the disc.
Don't rely on Nero DiscSpeed to check ANY Disc for quality as it does not read the disc at 1x rate, so ALL discs DVD or Blu-ray that show up as "Damaged / Unreadable often work perfectly OK in a normal DVD / Blu-Ray Player.
