Many people are not aware that they shouldn’t store their Blu-Rays in DVD wallets - it can lead do readability problems and false alert on degradation. Basically nothing should touch the BD recording surface for prolonged time period.
For the purpose of this experiment I burned two identical disc from the same cake/batch. One of the discs was stored in jewel case and the second one was stored in dvd binder for 100 dvds. The binder is full to its maximum capacity, zipped and stored vertically.
Writer: Pioneer BDR-209EBK fw. 1.34
Media: Omega BD-R 25GB 6x
Burned on: 28.01.2018
Scanning drive: hp TS-LB23L (DVD-RW/BD-ROM slim type drive)
Initial scans made on 28.01.2018:
Disc stored in DVD binder - initial scan
Disc stored in jewel case - initial scan
Scans made on 24.02.2018:
Disc stored in DVD binder - one month later
Disc stored in jewel case - one month later
When I removed the disc from the binder it had dust particles on the recording surface. First I tried to clean it with air blower but it didn’t help, the particles seemed to be glued to the surface. Second I tried to gently brush them off using lint free towel but that created smudges all over the surface. I had success cleaning the dust particles and smudges using the lens cleaner that I use for my DSLR lenses. After few tries I managed to make the recording surface shiny and smudges free. After all that cleaning I did the scanning.
This is an ongoing experiment - the disc are back in their storage. I will report back with new scans in month or two.
