Vast capacity and accelerated data transfer
Professional Disc for DATA achieve unparalleled 23.3GB storage capacity per
side together with 11MB/second read and 9MB/second write speeds.
Media durability of at least 10,000 rewrite cycles
Professional Disc for DATA media has been tested by Sony to provide at least
10,000 rewrite (erase/write/read) cycles and at least one million read cycles.
Blue-violet laser and high-performance lens
Professional Disc for DATA uses a short 405nm blue-violet laser.
Furthermore, the lens NA (numerical aperture) is raised to NA 0.85 for
considerably higher convergence. This combination of blue-violet laser and NA
0.85 lens creates a beam spot only one fifth the area of a DVD beam spot, so
much more data can be packed into a smaller space.
Track pitch narrower than half a DVD's
A narrow track pitch lets more data be recorded within the same disc area.
Sony's advanced stamper technology creates a track pitch of only 0.32μm.
High tilt margin with thin protective layer
The result is outstanding read/write stability with a tilt margin on a par
with the DVD format, while using a beam spot only one-fifth as large.
Rugged new cartridge design
It is constructed to not only seal out dust but also prevent damage of all
kinds.
The cartridge is made of tough, heat-resistant polycarbonate with anti-static
polymer for the lower shell and rotary shutter to enhance dust resistance.
50-year or better archival stability
Sony test results show an estimated lifespan of 50 years or more for data
stored on the Professional Disc for DATA at room temperature.
Hard case protection
A robust shock-resistant polypropylene case is provided for storage and
transport.
