DataPlay is an optical disc system developed by DataPlay Inc. and released to the consumer market in 2002. Using very small (32mm diameter) disks enclosed in a protective cartridge storing 250MB per side, DataPlay was intended primarily for portable music playback, including both pre-recorded disks and user-recorded disks (and disks that combined pre-recorded information with a writable area).
DataPlay included an elaborate digital rights management system designed to allow consumers to "unlock" extra pre-recorded content on the disk, after the initial purchase.
The recorded music industry was generally supportive of DataPlay and a small number of a pre-recorded DataPlay disks were released, including a Britney Spears album. However, as a pre-recorded format DataPlay was a dismal failure.
