A mini-CD performs the same function as a CD, albeit on a ‘smaller scale’. As its name suggests, it’s a miniature version of a CD.
It is 80mm in diameter (3 1/8-inch )(3.125 inches) as opposed to a regular CD which measures 120 mm in diameter.
mini- Audio CD
A mini-audio CD is also known as CD-3. The 3 refers to its diameter in inches.
A mini-CD (CD-DA) can hold up to 20 minutes of audio data. A regular audio CD holds 75 minutes of audio.
But then most mini audio CDs don’t always hold 20 minutes of music. For example, a Bruce Springstein CD-3 holds only two songs – One Step Up and Roulette. The total playtime is 8 minutes and 12 seconds.
A mini-DVD has the same dimensions as a mini-CD. It only differs in storage capacity.
A standard DVD holds 4.7GB of data. A mini-DVD holds 1.4GB of data.
Business Card CD
A business card CD is a mini-CD-ROM cut into the shape of a business card. It can hold up to 50MB of data.
You can use it to promote your business. For example, you can put an auto-run PowerPoint presentation that promotes your business.

How to Play a mini-CD
When it was first released in the late 1980s mini-CD or CD-3 required an adapter to play on your CD player.
But then if you were buying an audio CD, the adapter was included.
Newer players supported mini-Disc though.
Sony Pocket Discman
Sony introduced this personal CD player exclusively for mini-CD playback. It is also called a mini-CD Walkman. With a size of about 4 square inches, it comes with a rechargeable battery lasting 2 hours back in the late 1980s.
Back in 1988, it cost $360. It was Sony’s attempt to provide a disc version of its popular cassette Walkman.

You don’t need a special player to play a mini-CD these days. A mini-CD can fit into a regular disc tray of a CD/DVD player or a computer CD/DVD drive.
It is designed to sit on the inner ‘well’ of the tray.
