I have some discs made by CMC.
Suprisingly, these 3 different types of media have the same ATIP even though the quality is obviously worlds apart
This Disc is designed for CD-RW/COMBO Drive Only.
Disc Type, Material = CD-R, Phthalocyanine
ATIP Lead-in = 97m 26s 66f
Norminal Capacity = 702.83MB (79m 59s 74f)
Disc Manufacturer maybe = CMC,Imation
SMART-BURN Speed Limit = 48X
Verbatim Datalife (not plus) Crystal 24x
The label side feels sticky for some reason. I bought 10 pieces, they stuck to one another
and i had to sort of pry them off one by one. They work ok at 8x, i only had a 8x burner (panasonic) when i bought these discs. I would say decent quality.
: I just discovered some bad files on my Verbatim discs. This sucks
When I tried to open some bad gif files, Internet Explorer (my gif/jpeg program) said something about offline (?). Other good picture files work fine though.
Unbranded Discs (Labelled 40x by the store)
Silver top, silver bottom. My friend uses these garbage to pass me stuff. These don't work without errors at 32x and above. Impossible to remove fingerprints from the label side. He uses a Plextor 40/12/40 clone.
Unbranded Discs Part 2 (Labelled 40x by the store)
Another batch of wonderful silver top/bottom discs bought by my friend. These are total garbage. The discs are not even molded properly, bumps/impurtities can be seen. The middle of the discs look different from the Unbranded discs above, so they're probably churned out from different machines/plants. Why they have the same ATIP, I have no idea. Don't work at 32x and above.
