I have a Phillips CD recorder that was given to me from a coworker. Up until a few days ago, I'd only been using it as a cd player since I have a CD-RW on my PC for making CD's. However, I thought it might be fun to record some audio from those music channels on my cable service. Anyway, I drop a CD-R in the player and it doesn't recognize the disc. After reading the manual (usually the last resort for me ), I can only use CD-R's with this logo: What is the ultimate difference between these disks and regular CD-R's with this logo? Just curious.
