Maybe this will clear a little up here.
The reason that a CDR burner in a computer is more suitable for creating "master" CD's is the fact that it will burn DAO (Disk At Once), where a stand alone player burns TAO (Track At Once).
This is only really an issue if you are going to send your finished CD in for duplication. In the past, duplication houses would have to re-master a submitted CDR that was authored in the TAO format because for them to just copy a disk to a glass master, they needed to have a disk that was burned where the lazer did not stop anywhere. There is a whole bunch of boring technical issues involved with trying to copy a CDR that was burned in TAO mode to glass master that I don't feel motivated enough to look up again and expand upon.
Anyway, times are a changin'! A lot of duplication house now can accept CDR's burned in TAO mode to make glass masters from. Not all can, so if you are sending your burned CDR in for duplication, you should check this with the plant that will be making them for you. They may or may not be able to use your CDR burned in TAO mode to make the glass master from. If they can't, they can re-master from your CDR, but usually this will entail a fee for their mastering services, and if they do this for you, make sure you specify that you don't want any compression or EQ applied, unless you actually do want it applied. Many times in the past people I have known have sent in their CDR masters to duplications houses to get back 1000 CD's where an over zealous house mastering engineer applied bad compression and/or EQ to the mastered songs that the client didn't want.
If you are going to use the duplication houses mastering service, MAKE SURE THAT THEY SEND YOU A REFERENCE CD FOR YOU TO HEAR BEFORE THEY DUPLICATE FOR YOU!!! And if you are paying for this service, scrutinize the mastering job really closely before you say yes to what they did! Often, you will just be impressed with the hotter levels and somewhat better eq. But often, if you listen a few times, you will not like what they did as much. Likely, the mastering engineer is a kid right out of Full Sail who is getting his feet wet in mastering. Basically may not know what he is doing. So, if you don't like the job he did, ask for it to be changed to something you will like and ask to be sent another reference disk. This is time consuming, and at some point, if you are really picky, you will be paying extra for the extra mastering. This is why I suggest you either have your disk mastered by a mastering house where you can set in on the session and walk away happy with the results, or master yourself and specify that if the disk needs to be reauthored by the duplication house that it is not compressed or Eq'ed when they do.
So, what MISTERQUE is saying is partially true, but not as pertinent now that many duplication houses will accept TAO mode disks.
Also, duplication houses need an EXACT time sheet of your mastered disk to make a glass master from. On stand alone units, you only get a Min./Sec. count on the display. The duplication house needs it down to a hundreth of a second. With CDR burning software on a computer, you can print out this Time Sheet to send to the duplication house and it will be exactly what is on the disk.
