Mt Rainier Rewritable Validation Suite - Page 1
As it is already known, the Mt Rainier Group (Compaq, Microsoft, Philips and
Sony), propose an open industry standard for making CD-RW easier to use by enabling
OS support and increasing compatibility and performance. The name of the new
standard was named after Mount Rainier in the US state of Washington at the
foot of which Microsoft has its headquarters.
The Mt Rainier format is mainly applied to general storage data applications,
or "Drag&Drop on CD-RW". However, writing data (Drag&Drop)
on CDs is currently not supported by any operating system. The functionality
is currently handled by special applications that need to be installed on the
PC running the drive. New CD-RW discs need to be formatted before data files
can be written to them. The objective of the Mt Rainier solution is to overcome
these issues by enabling native OS support of the drives and allowing CD-RW
to be used as a "Drag&Drop" device by choice.
The main elements of the Mt Rainier format are the physical defect management
by the drive, the logical write addressing at 2K, the background formatting,
the command set implementation and the compatibility and standards-compliance.
All the Mt Rainier CD-ROM / CD-RW drives should be compliant to those specifications.
Currently the UDF 1.5 file-system used in Drag&Drop applications handles
defect management. The Mt Rainier proposal for adding physical defect management
into the drive, allows more commonality with standard data-drives (DVD, MO
The logical addressing capability of the storage devices is also an important
factor. The Mt Rainier functionality has defined 2K logical addressing as a
mandatory support requirement for drives.
The Mt Rainier specification allow user to Drag&Drop data within seconds
after insertion and spin-up of the disc. The disc formatting process occurs
in the background, and the Drag&Drop data storage tasks should get priority
above process of "de-icing" and "finalization", by the drive.
For a Mount Rainier compliant drive, implementing a mandatory command-set for
data-use is required (fitting the MMC-2 structure).
