Re: Saturn CD Drive Duty Ratio Restrictions

When developing CD-ROM software for the Saturn, note the following restriction:

The duty ratio of the Saturn CD drive must be 33% or less after approximately 10 minutes.

This restriction is due to a CD drive limitation.

• Duty Ratio Definition: Duty ratio = [seek time/(seek time + nonseek time)] x 100

Note: Nonseek time refers to the time used for operations other than seek (such as play or pause).
