Not necessary disagreeing with the response but being more detailed.
In order to read CD-R & CD-RW a the reader must by "multi-read" capable.
Some order readers will read CD-R and not CD-RW. Some will read neither.
Newer readers will also not read them if they are not multi-read.
Besides PC readers, this situation applies to audio readers also. I have an
old (years or more) audio reader that reads all three formats fine. I also
have two new (less than 2 years) portable audio CD readers that will only
read CD-R.
They do no use different "format" in the way I define format. The inability
to read has to do with hardware not software (format). The reflectivity of
CD-R and CD-RW are less than a standard CD. CD-R & CD-RW use a colored ink
that is changed during the "burn" that makes the "holes" the reflect back or
not. Standard CDs actually have holes in them with a mirrored surface under
the holes. That is cause of the less reflectivity in CD-R & CD-RW. The
inability to read these less reflective disks has to do with the laser
frequency and power.
