Review on 💿 Optical Quantum 50 GB Blu-ray Double Layer Disc - High-speed 6X BD-R DL Logo Top, 50-Disc Spindle by Joshua Mccall

The reports from other users confirm that the quality of the discs currently sold is no longer high enough to be sold. They should be banned from selling on Amazon. See below: Using LG WH14NS40, writing continues, but all discs fail imgburn at 51% (Layer Tear), "Medium Error, Fatal L-EC Error" (see photo). The resulting disk files could not be read. I have confirmed that another LG WH14NS40 device still gives me this error, which rules out the drive as a problem. I have re-ordered the same discs and this is still happening (order date January or July 2019) with the exception of a defective disc spindle. However, the old batch of discs I had (bought in January 2018) burned and tested just fine. Therefore, the quality of an optical quantum disk is poor. Verbatim 50GB BD-R DL VBR260YP20SV1 discs are usually written and verified on the same drive. If you copy the files you will notice that at 50% layer tearing the speed drops from >25MB/s to 8MB/s. See attached diagram - it regains its speed later when recording. This effect is not observed on Verbatim 50GB BD-R DL VBR260YP20SV1 discs recorded in an LG or Pioneer deck. Therefore, new batches of Optical Quantum 50GB BD-R DL OQBDRDL06LT-50 are not of sufficient quality to be used. in the LG drive, and those burned with the Pioneer drive clearly can only read at a lower speed, which is unacceptable. As someone who has been buying ONLY Optical Quantum Discs for the past 10 years, I am very disappointed that they have changed their production and that my Amazon return window has closed leaving me with $90 discs that cannot be used. I want my money back! UPDATE: I tried shooting on 4x and it shot and verified correctly in LG WH14NS40. It also copied to the Pioneer BDR-209DBK without reading problems when the layer was broken, as in my image 6x. An optical quant shouldn't call them 6x if they can't do 6x (more). So in summary: Disk ID: RITEK-DR3-000 - BAD OPTICAL Quantum (Disk ID: RITEK-DR3-000 and for a good batch) Good at 4x in LG WH14NS40. found max at 6x and worked at 6x on older discs...there was slow copying after writing to Pioneer at 6x - issues just over 50%, consistent with layer tearing issue. Drive ID: RITEK-DR2-000 - SMARTBUY drives, only 4x! works fine, copies normally. Disk ID: VERBAT-IMf-000 - VERBATIM Recognizes as 8x and writes as 8x perfectly. Disc ID: CMCMAG-DI6-000 - XTREMEPRO Recognizes as 6x and burns as 6x perfectly (advertised as 4x so bonus)
