Hi All,I just read this info on a forum on the net regarding the dreamcast.
Intresting how the Sega Saturn compares?
2.1.1 What is a GD-ROM?
- GD-ROM stands for Gigabyte Disc Read Only Memory. Sega decided to use a
proprietary compact disc system, for two main reasons.
One was to fit more on the disc; standard CD-ROMs have a maximum capacity
of between 650 to 690 Megabytes, while Sega's GD-ROM's have a maximum
capacity of up to 1.2 Gigabyte of data. The second reason was to discourage
the casual pirate, as the GD-ROMs are not copyable in a standard CD or DVD
writer. (nor are they entirely readable in a CD-ROM or DVD-ROM drive.) One
part of a GD-ROM can be made readable on a standard CD-ROM, and Sega and 3rd
party developers often use this section of the GD-ROM to include some
pictures for computer backdrops or other items related to the game, as an
extra. It is also possible to include audio CD tracks that play in a
standard CD player, and most GD's have at least one audio track warning the
user not to play the GD-ROM in a standard CD Audio player. Try it! The
voice is usually corny and fairly amusing
To fit more data on the GD-ROM disc, the data is written in a slightly
different format to regular CDs. This may mean that the GD disc is actually
more sensitive to scratches and defects than regular CDs too.
Thoughts anybody?
Looks interesting............. :bow
