パイオニア
In the early 1990s, Pioneer Corporation deployed a variation of the 30-cm LV-ROM with a different file system and a 540 megabyte capacity. This disc format, called LD-ROM, stored the software for a home entertainment system that Pioneer introduced in 1993. This system, the Pioneer LaserActive, was a cross-platform video game console, Laserdisc player, and CD player.
