It is most important that you first realize that only one cdrom disk is used.
for both styles.
You will see two different types in the stores to buy.
One will say music, the other will say data, back up CD, or just be blank.
That is a little trick to get more money out of you.
The Record Company's known as RIAA came up with that trick, They get a percentage of the money paid, to buy those cdroms labeled music.
They figure if you are going to get music from on line and burn it.
And then give it to people for free, they will get you to pay for it by buying the music CD disks.
That is the only reason the disks have the word music on them.
Nothing is done to make the disks different except print that word music on it.
Okay here is the best way for someone to understand the difference
in the two styles of cdroms used for music.
1. First the music cdrom.
This is a style of cdrom that is best thought of as the old style vinyl
records. Using that line of thought you can understand what it is.
The vinyl records have two sides with grooves in for the songs.
Each side is about 30 minutes in length of music.
The music style of cdrom is one sided and has laser light grooves in it
that are 80 minutes long. So it uses a laser instead of the needle like
the turntables do. this style of cdrom is called Audio,.
2. Second the data music cdrom
This is a style of cdrom that is best thought of as the storage case for
your old style vinyl record albums.
Meaning that it holds the album with all the songs on so you can get
more then 80 minutes of music.
This is done by putting files on the cdrom just like saving files on your
hard drive.
Now that you know the differences you must know that only the first
style will work in all cdrom players either in the computer and or the
automobiles.
For the reason it is like the old vinyl and does not need huge amounts
of code for the player to see the songs.
It just guides the laser light along the groove and reads
the bumps / dots and dashes to play the songs.
The second one has to have more codes in the player's computer system
to be able to open the album case and read the song file.
Now some of the cdrom players do have the extra code and can see
the data cdroms, but if you try one of this style and it does not play.
Then it more likely is because the player does not have the extra code.
That is the best way I can say the difference between the two styles.
I hope that has helped you understand them.
