CD recorders are supposed to write their RID code in the main channel of the Table of Contents Items in the PMA of CD-Rs that they record. This is useful information to companies like mine that write lots of discs on lots of recorders. Most notably, when QA discovers a marginally written or defective disc, it is imperative to know which drive wrote the disc so we can get it out of service.
We can get at the RID code the hard way, i.e. feed the PMA RF data coming from our tester into a TIA and go through all the decoding necessary to recover the main channel data. But this takes time and trained personnel. What we’d like is a simple way to get at the RID code data that could be implemented on the shop floor.
Any CD Freak out there who knows how to make that happen?
