To achieve 9.1GB storage capacity, Sony's 5.25 MO disk employs MSR (Magnetically induced Super Resolution) and Land & Groove Recording technologies. This enormous capacity is 14 times the 650MB of Sony's first-generation MO disk.
Sony's wide-margin media is designed to be highly tolerant of variations in laser power that may occur in different usage environments. Performance stability is further assured by Sony's high-precision stamper and substrate molding technology.
With data integrity maintained over at least one million erase/write cycles and a data-read life estimated at more than 50 years, Sony 5.25 MO media is highly suited to long-term data archiving.
Sony uses its own rugged cartridge design and mechanical components to achieve durability of at least 100,000 load/unload cycles per side. Sony's original antistatic hard coat treatment reduces static buildup and protects the disk surface from scratches and dust.
With MSR (Magnetically-induced Super-Resolution) technology, the recorded magnetic domain at the center of the laser spot is selectively heated to transfer its data individually to a special readout layer. This makes it possible to distinguish magnetic data that is much smaller than laser beam spot size.
Besides writing data in the grooves like a conventional disk, this format uses the "lands" between the grooves as well. Land & groove recording creates two spiral data tracks to dramatically raise data density and disk capacity.
With its high-speed random access and massive storage capacity, the 5.25 MO lends itself to a wide variety of applications. MO drives can be easily connected to PCs and workstations including LAN and Web servers to handle computer graphics, CAD/CAM, X-ray and ultra-sound medical images, non-linear audio/video editing, and government agency or library document archiving. Other popular applications include large-scale libraries and jukeboxes that depend on high-speed disk changes.
