The lasers in older game consoles are very weak and they get even worst with age. They don't tend to do well with many scratches. The disc may read in a PC with scratches, but then fail to load in the console. I have found PC drives to be far more resilient to scratches compared to consoles.
In the case of PlayStation 1, in the interest of space, they went with mode 2 XA format which makes the discs lack error correction codes. This means if the disc fails in a PC it definitely will fail in the console with no way to correct.
