CD Text – Text Encoding
This is NOT the track info you see when you play a CD on a computer with iTunes or Windows Media Player. (See Getting your CD track info to show up on computers)
The artist, CD title, track names, etc. are encoded onto a CD like a table of contents. It enables certain CD players to display text information such as artist, title, track names … etc. It can only be read in players that support CD text (usually in cars or multi-disc carousels) and usually have an LCD display which scrolls the song info while it is playing each track.
This is encoded into the master, and not each track, so if you submit individual tracks for duplication, the cd text encoding will not transfer with it.
Track Info for your Computer

This information is usually then stored on your computer. It is NOT encoded on your disc. [READ MORE]
