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 at any time following 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 failure. There were very few products seen on the market that could write data to these discs. Most notable was the Topy Mini Writer, which retailed for $130 (USD) and housed an optical pickup unit (image №4) with a USB interface board, allowing the use of DataPlay discs much like other end-user writable optical media (e.g., CD-Rs). Other noted products were the iriver IDP-100 and the MTV Video Device "MTV FLIP", which both housed the prototype-based model (image №2). As of 2012-01-14 it is extremely hard to obtain any DataPlay items, as they have not been produced in some time; they are quite rare, unless found on a surplus or auction website catering to collectors or aficionados looking to obtain them.
