Multimedia, AV "Sony has announced it is to deliver its last MiniDisc stereo next month. It marks an end to the firm's support for the system which it launched in 1992. The format only ever had limited success outside of Japan and was ultimately doomed by the rise of recordable CDs and MP3 players." My format of choice for personal audio up until a few years ago, when the rest of the world had already long moved on to MP3. Nothing beats the satisfying sound of closing a portable MiniDisc player/recorder with a disc in it.

It's Sony and Fujitsu who invented the magneto-optical system. First ever used was the 21 MB floptical in the Next, then the 128 MB, 230 MB, 540 MB, 640 MB, 1.3 GB and 2.3 GB in 3"1/2 format, and some similar sized 5"1/4 disc with 5.2 and 9.1 GB, before UDO.

I still use nowadays the 1.3 GB 3"1/5 and the 9.1 GB, pretty efficient yet very slow at writing. The later fitted in a HP SureStore 20 XT magneto-optical SCSI juke box ;)

The recordable optical disk was invented by David Gregg whos patents was later owned by MCA. And i remember using LD (LaserDisk) disks in the 70's at home, long before NEXT even existed. And if you mean the CD, then also no. It was developed by Phillips (and later Sony in conjunction). The GD-Rom was developed by Yamaha. And the Phase change ones used in many home systems was developed by Panasonic. The ones used in NEXT systems was magnetodisks and more of an optical floppy relying on the Magneto-optic Kerr effect.
Edit: First sentence made no sense so i removed it.

Magneto-optical, read by laser (phase change due to magnetic effect), written by laser (heated to curie point) and magnetic head (polarity change).

Plasmon also made some MO devices. Iomega tried to enter le market (I have some 1 GB MO disks), Sony, Verbatim, etc...
