I wrote to two very knowledgeable cdfreaks by private post. As a 70 year old newbie I had no idea about how to start a thread. Here’a a sort of summary of my private posts and responses now that I see how a thread starts.
I ordered Taiyo Yuden CD-Rs from a site recommendd by Pricegrabber and got a box that didn’t look right.
I have searched unsuccessfully for a list that identifies the code or letters blind stamped on the clear inner ring of the CD-Rs. As far as my failing eyes can make out, the CD I want to identify reads
2B7680 ? 73409A09794802B7680D
I could be wrong about some of the letters or numbers. The first letter B could be an 8. The ? looks like an R surrounded by a circle but it is hard for me to make out.
Responding to kg_evilboy, I wrote
The transparent part of the disc is not frosted.
The code on the underside reads
It’s on the light blue ring adjacent to the main part of the disc that gets the data burned into it. Going oward the center, there’s a silver ring, the underside of the shiny top then the transparent part that’s not frosted.
I have genuine TY discs that are frosted, code begins KC
By theway, I use a Mac and can’t read the PC software suggested for DVDs.
Is there any Mac software that tests DVDs or CDs?
Thanks for any suggestions
