BACKGROUND OF THE INVENTION

Digital storage systems are utiliZed to store digital assets
such as video, audio, executable and non-executable com
puter programs, and data ?les. These systems generally
utiliZe magnetic or optical media. Some systems, primarily
of the magnetic type, are capable of a multiplicity of
read/Write cycles, While other systems primarily of the
optical type, are capable of greater data storage densities but
15
are usually limited to a single Write cycle With a multiplicity

Thus the prior art teaches multi-layer optical discs, dual
sided optical discs, multiple data formats, and readers
capable of reading multiple formats. HoWever, the prior art
does not teach a dual sided optical disc having different
formats on opposing sides.
SUMMARY OF THE INVENTION
The present invention teaches an optical disc having at
of read cycles.
Although entities producing digital assets on optically

readable discs may do so in a variety of formats, end users

commonly have the equipment to read only a subset of the
group of available formats. Because each format has an 25
inherent set of available features Which may lend the format
to a particular type of digital asset, producers must limit
themselves to the production of discs (and therefore the
content features) having that combination of features
required by the content Which is most readily readable by the
30
intended end user.
Digital assets are commonly Written to 12.0 cm optical
discs in one of the folloWing formats:
