Hi,

A conventional multi-session run.
So far so good.

Here we learn the Next Writeable Address of the

That will be a TAO session with CD-ROM Mode 1
sectors.
Known to work fine ... but:

Reader devices do not necessarily expect a
mix of audio and Mode 1.
The CD-XA specs are said to demand that all
tracks in such a mix have to be Mode 2 Form 1
or Form 2. (One can find traces in MMC and
in ECMA-168.)

On a computer you can expect this to be well
readble. But what about older CD players ?


The cdrecord recipie i am looking for would
use options like -xa1 , -xa2 , -raw ...
Important is to get a confirmation that the
result really complies to the semi-secret specs.
I could then use cdrecord -V to learn about
the involved MMC commands.


Have a nice day :)
