CD/DVD reading issues with Macs
Numerous people have complained about CDs and DVDs reading and writing on Macs.
Often it is because they don't realize how CDs differ on many Mac drives.
The biggest issue often arises because one doesn't follow this
Apple knowledgebase article
After that these concerns have been noted on various boards:
1. Use of sticky labels on discs. Buy discs that come in a jewelcase, and
use the inserts for the jewelcase to indicate the contents of the disc.
2. Use of ink on the label of the disc. It can affect the reflectivity of
the disc. See point 1 for avoiding this issue.
3. Burning disc at maximum speed for the drive. Some drives are slightly
out of sync and can't read from the maximum burn speed.
4. Buying disc on a spindle. Unfortunately this allows discs sometimes to
scratch each other. See point 1.
5. CDs are best made by Verbatim, Kodak, Imation, or Sony.
6. DVDs are best made by Ritek, Verbatim, and Taiyo-Yuden.
7. Discs that have non-standard formatting. UDF and Joliet are less
standardized than ISO-9660. A few discs have special movie extra computer
addon software that is only playable via special software. If you can find someone still selling, Software Architects ReadDVDMac (the company no longer exists),
it can handle some UDF and Joliet formats.
Interactual's Player plays some of the extra content that the
built-in Mac software can not. For other software, a
virtualization solution may be necessary.
8. Dirt on lens. If your machine is in warranty, have the drive serviced to
verify dirt didn't get on lens. If it is out of warranty, find a safe to
use lens cleaner for notebook optical drives.
Issues have cropped up where ejecting the disc becomes difficult. For that I've written
a short script called Eject Disc
9. Sometimes discs eject as soon as they are inserted. If the reasons are not the ones
above, the most common reason is either a dead PRAM battery, or if the machine is under 4 years old,
a need to zap the PRAM.
10. Bluray discs are not Mac readable by default. See this user tip if you have a Bluray disc.
