These were the graphs and now a few diagrams with numerical results:

This benchmark was run with the three disks from the previous test and with a licensed audio CD. The graphs above indicate that Sony DRU-500A fully complies with its specs. Again, it works well with any medium type. The only point of difference among the disks used is the recognition time. The drive recognizes CD-ROM and audio CD twice as fast as CD-RW or CD-R.
