Cannot tell if this media is LTH or HTL bd-r

[Dannyboy1985]

Hi guys I recently purchased some tdk life on record bd-r from eBay in a 10 pack spindle. Ive always used tdk life on record with no issues but not printable. These are printable and carry the life on record brand and can write 1 to 6x. I checked the relevant thread and it says tdk 1 to 6 x discs are HTL. But on closer inspection of the image ( I have not recieved these yet and returning them would be easy ) there is something that says imation Corp on the label of the cake box. Is this another company tdk has outsourced manufacturing to? I guess I can wait until they arrive and see if imgburn can see if they are htl or lth. Thanks guys.

Yeah thanks ive just researched more myself and had no idea this happened all the way back in 2007. Thanks for the article but now the question is are imation bds lth?

Those are made in Taiwan, which means they are probably Ritek or CMC Magnetics made discs. I doubt they are LTH.

HTL discs are generally much darker on the side holding the data (not the label side) verging on black if not completely black. LTH discs are generally very light on the data side, with discs I currently own being a light golden color. Has to do with the difference between organic dyes which are used in LTH and inorganic dyes which are used in HTL. Every manufacturer tends to use their own proprietary dyes which might lend to some variance in the colors within the same format (HTL for example).

A good general rule is that if the label does not say LTH, then it's a HTL.

Another way you can tell if it's LTH is when doing a scan and it only goes to 6x for all the discs in the pack.
