An ATRAC CD is a compressed audio optical disc containing compressed digital audio in the ATRAC3 or ATRAC3plus formats, which are part of Sony's ATRAC (Adaptive Transform Acoustic Coding) family of proprietary audio compression algorithms.

ATRAC CD was used with SonicStage Simple Burner software (Ver.1.0 / 1.1) in February 2003,^[1][2] and was subsequently replaced with SonicStage in 2004. The new CD Walkman product was called "ATRAC CD Walkman". In the following year (2004-2005), ATRAC CD boombox was introduced, as a new product.

The ATRAC CD can be burned with SonicStage Simple Burner Ver.1.1, SonicStage 2.x to 3.x and SonicStage CP. This software is able to create a disk image from MP3 files and compact discs and can be burned with the included CD-R/RW drive on a computer.
