Hey guys,
i dont have a 93 bose so I cant speak from experience, but maybe i can shed some theory on the the topic.
Cds are impressed with physical 'bumps' (i guess technically the holes are impressed, but regardless it has a series of pits). The pits and bumps reflect the laser differently and voila you have binary data.
The cd-r sort of plays on this. The cd-r has a certain color substrate. When heated by the laser, the chemical changes properties and, once again, you have areas that reflect light differently and then the reader can read binary data. Cd-rws are similar but of course, can be changed back to original state.
The problem is that the laser is not as strongly reflected. I guess this can lead to the laser operating at max powert the whole time, but sometimes this isnt enough for low-reflective cd-rs. I know people who have physically altered the circuits to overpower the laser so it can read. This has been done on Playstations so it can play certain cd-rs or dvd-rs (i think) and also on dvd players (dont forget cds and dvds are pretty much exactly the same in princple).
Different cd-rs will reflect differently i guess is all you can take away form ths, but you've already discovered this.
I don't believe this is a finalizing issue. Most players will not play an open disk. Also I didn't know you could alter the file scheme. As far as i know the audio cd mode uses different block structures than the data schemes and also trabnslates into different recording times between data and audio.
hope this wasn't too technical and some of you were actually interested. When i upgrade my stereo, I'm putting a computer in.
