Blue ray disc drive hardly eject or receive disc

So, I have this problem with my PS4 pro. I have opened the disc drive to clean dirt from it, I have checked for any visible damaged gears, I have cleaned the rollers, in the drive but the console cannot take CD easily. If I place a disc in the drive it doesn't accept it easily unless I push very hard before it goes in , even at that, it doesn't sit for it to spin to start, I will have to use the tip of a flat screw driver to push the disk that has not fully gone in before it will now spin to play, Also, when I eject disc, it only comes out a little such that I can only use the tip of my finger to drag it out. Please, what cold be the cause? What can I do to fix it? As I now, I can only play one cd that is playing on my console because I can hardly eject it. Please does anyone know what is wrong with my console. I was told by a repairer that the drive is becoming weak, I was told by another that it caused by a bad Hard disc drive. I do not know which is true.
