Applications For Cd-Recordabie - Philips CDD522 Operating Instructions Manual

APPLICATIONS FOR CD-RECORDABLE
From the applications point of view, data is to be organized so
that it can be easily accessed, either by man or machine.
There is a large variety of applications, each of them relies on
specific characteristics of the medium. They ail have to be
covered by the same system. Some of these applications are:
- Software Distribution: the compact disc should mimic
the target filesystem. The benefit over distribution on
tape is the small reproduction cost (stamped disks).
- Data archiving: the compact disk should mimic the
target filesystem as above, but in addition features
"data appendability", i.e. the possibility of appending
new data at various points of time, without loosing
the previous data. This type of applications would
use CD-R (Compact-Disc Recordable) discs, since
the data to be archived has to be written by the
system itself. Its benefit over other archiving media is
the standard interchange, the easy access
(compared to tape), the 600 MByte data capacity,
and its expected disk life.
