On the player there must be the loge CD-R compatible. If not, it wont play CD-r disks.
Normal CD's have a metallic reflector layer, giving a high contrast. CD-r disks have a dye, that will be changed in colour by a laser, giving a lesser contrast. When the laser and detectors in the player is not capable of reading the lesser contrast they can't play CD-R disks. Most older players can't. Sony is one of the manufacturers who deliberately kept there players incompatible with CD-r disk the longest.
The last 3 discs might be CD-RW which can be rewritten, but not all cd players will be able to read them. Just go to the store and buy some CD-R disks and re-burn the last 3 disks. That should solve your problem.
the lens on the optical pickup is dirty and needs cleaning. they sell a lens cleaner disk at any electronics store. you also might want to blow any dust out of the unit with canned air to prevent it from happening again.
