Are you asking how to read data that is not on the disc? That's hard.
I think what you meant was how to get the album title and song titles. If you import the CD into iTune then iTunes will querry the on-line Gracenote database and pul down the I thin iTunes ignores the ISRC data and always goes to Gracenote.
Other software can querry the database or other ones like it. XLD does a good job of this
