Robust construction for auto-changer use
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.
Magnetic data resolution finer than laser spot size
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.
Land & Groove Recording raises data density
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.
Widely adopted for demanding applications
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.
