Are you burning audio or ROM discs?
Do you use professional recorders or standard consumer drives?[/QUOTE]
We are writing data, not audio, using professional recorders, not consumer recorders. In addition, we are writing an image using commercial equipment that does not allow us to insert information that is specific to each drive.
We are writing a single Mode 2 Form 1 track in a single session, apparently in track-at-once mode, leaving the disc open for append. So it is possible that there is RID information in the main channel of the PMA and/or of the link blocks - two locations for which I have yet to find an easy means of access.
BTW, what type of tester do you have that streams the RF out for you?
We have an aged, yet phenomenonally functional, piece of test gear made by APEX that allows us to test both unwritten and written CD-R media. It has all sorts of analog outputs including RF. We can order it to any radius, instruct it to lock the motor speed to the data, then capture the RF signal.
