Due to the restrictions on the CD drive, please note the following when developing CD-ROM software for Saturn.

◆ Make sure that the duty ratio of the Saturn CD drive is within 33% in 10 minutes.

Definition: Duty ratio = [Seek time / (Seek time + Non-seek time)] * 100

Non-seek time is the time other than seek (play, pose, etc.).

that's all
