MultiLevel Recording is a technology originally developed by Optex Corporation and promoted by Calimetrics to increase the storage capacity of optical discs. It failed to establish itself in the market. Through a combination of proprietary media, recorder, reader, and player modifications, Calimetrics proposed that ML could increase the capacity of a CD-ROM, CD-R, or CD-RW to 2 GB; a single-layer DVD, DVD-R, DVD+R, DVD-RW, DVD+RW, or DVD-RAM to 7.1 to 10 GB; and a single-layer Blu-ray Disc (BD) to as much as 60 GB. An optionally integrated digital rights management (DRM) system called MovieGuard was also suggested. An industry group called the ML Alliance was formed in 2000 to help commercialize ML technology. Members eventually included Calimetrics, TDK, Sanyo Semiconductor, Plextor, Matsushita Kotobuki Electronics, Mitsubishi Chemical Corporation, Verbatim, TEACr and Yamaha.
