GDROM

GDROM is a proprietary optical disc format developed by Sega for its Dreamcast video game console. It was also used in some arcade hardware. The GDROM format uses a 12 cm disc, similar to a standard CD or DVD, but with a higher storage capacity. This increased capacity allowed for larger game worlds, higher quality audio, and more detailed graphics compared to previous console generations.

One of the key features of GDROM was its data transfer rate, which was significantly faster than that of CD-ROMs. This allowed for quicker loading times and a more seamless gameplay experience. The format also incorporated a copy protection mechanism, making it more difficult for pirates to create unauthorized copies of games.

GDROM discs were read by a specialized drive found in the Dreamcast and compatible arcade machines. The drive was designed for speed and reliability, contributing to the overall performance of the hardware it was integrated into. While GDROM was a proprietary technology, its implementation in the Dreamcast was a notable aspect of the console's hardware design, differentiating it from competitors that relied on more conventional CD-ROM technology. The format's lifespan was tied to the Dreamcast's market presence, and it did not see widespread adoption beyond Sega's platforms.
