Re: Saturn Disc Format Specification Change

The standard specifications for the Sega Saturn disc format will be changed as follows:
Target: Disc Format Standard Standard Specification Version 0.9

1. Recording range in program area

                              ABS TIME         LSN          FAD 
First frame                   00:00:00           -            0 
First sector                  00:02:00           0          150 
Last sector                   63:01:74      283500       283650 
Last frame                    63:03:74           -       283800 
Read out area start time      63:04:00 

 

• The first frame and first sector must be the times shown above. The last sector and last frame must the times shown above or smaller values.

2. The following figure is an image of the tracks when the data track is maximized (audio track is minimized).

• The portion of the track that can actually be used as the data sector is from the first sector to one sector before the start of the post gap (approximately 566 megabytes).

For each minute that the audio track usage time increases, the data sector decreases by 9 megabytes.
