Audio CD aint playing!

problem is that i recorded on a CD TDK (dont think that i used shitty disk )
and i recorded 15 tracks… my system is LG and it played first 5 tracks and after it when i turn on the sixth, it shows that it is loading(disc icon is filling and unfilling) but it isnt doing anything…

what is the problem? other CD-s i record are working good…

Please Help
