Computer Disk

A MiniDisc: a recordable music disc that never leaves its cartridge. Sony launched the MiniDisc (MD) in 1992 as a pocket-sized, rewritable rival to the cassette and the CD. The disc is about 6.5 cm across and sits permanently inside a square plastic shell, so you could throw it in a bag without scratching it. You recorded your own mixes onto it, and portable MD players were everywhere in Japan, popular in Europe, and barely noticed in the United States. Downloads and the iPod finished it off; Sony built its last MD Walkman in 2013. The emoji comes from the Japanese mobile-phone emoji sets of the early 2000s, when an MD was simply what your music lived on, which is why its shortcode is :minidisc: even though Unicode filed it as “computer disk”.

On most keyboards it draws as a disc showing through a square case, often with a gold or orange label (as of 2026). If your screen shows something plainer, that is the same character.

What does it mean when someone sends 💽?

Usually music, sometimes files, often just a retro mood. Beside a song, album or playlist it means recorded music, the same job as 💿 or 🎵 but with a vintage shine; music producers and DJs like it in bios and release posts. Next to words like “backup”, “saved” or “files” it stands for data and storage. In a throwback post about old gadgets it is pure nostalgia, and a row of 💾💽💿📀 is a joke about how many formats we have outlived.

How it lands depends on age. Anyone who owned an MD player feels a specific pang; younger readers mostly see “old disc thing” and may assume it is a CD or a floppy. That rarely matters, because the loose meaning (music, data, retro) survives the mix-up.
