First hand-held videogame console with an optical disc

According to Official Guinness Records,

The earliest hand-held video game console to use an optical disc was the PlayStation Portable. The PlayStation Portable, first launched in Japan in December 2004, plays its games from an optical disc specially developed by Sony for the console. The Universal Media Disc (UMD) is a read only disc measuring 65 mm across and is held inside a plastic casing that slots into the top of the PSP. The disc is capable of holding up to 900 MB of data – 1.8GB for dual layer discs.
