This CD icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
Idea of CD Icon by bath
We've received the idea on October 13, 2012 and created the icons on January 8, 2013
I'm surprised that media format icons seem to be absent (or have I missed them?). The only one I found was LP record. I couldn't find CD, DVD, Bluray, Audio Cassette or VHS.
