Optical Platter Selection

       Disclosed are two method options by which documents
(objects) can be stored on optical devices.  The first is called the
"performance" option.  The second is called the "group" option.  The
option used will be specified by the system administrator.

      The Performance option directs the system to store a document
in Mixed Object Document Content Architecture (MODCA) on whatever
optical platter is currently loaded and active in the drive (i.e., a
"MOUNTED" platter).  The actual optical volume used will be
determined via callable lower level API services which interface with
the optical device.  The volume used will be stored in the database
maintained by the Storage Manager so the document may be accessed
from optical storage at a later time.

      By using this option, the user will have the document stored to
optical relatively quickly.  No waiting will be required to mount a
(specific) platter.  At the same time, however, the user will not
have the benefit of being able to group the documents on a given
platter.

      The Group option directs the system to store a document (MODCA)
on a specific platter.  The Storage Manager will maintain a table for
each optical device known to it.  Each table will contain a list of
optical volumes to use for a set of shared folders (i.e., Shared
Folder 1 is assigned Volumes 1-10, Shared Folder 2 is assigned
Volumes 20-30, etc.). Each user is assigned a default Shared Folder
