5.25-inch MO and WORM disks combine the qualities of high-speed random access and long archival life to suit a variety of applications including storage of diagnostic imaging, HIPAA and other regulatory compliance, non-linear audio/video editing, graphics processing, and document archiving by government offices and libraries. From 1X to 14X, Sony MO media is optimal for mission-critical storage environments that require both longevity and performance.

Sony MO disks offer consistently stable performance, thanks to the adoption of Sony's own Wide Margin Recording Film, which can accommodate fluctuations in the laser power of a variety of user environments, as well as a high-precision stamper and molding technology. The use of Sony's own cartridge design and parts gives Sony MO disks as many as 100,000 load/unload cycles per side for superior durability in auto-changers.
