Howdy Ralph,

At this time I don't expect the SSC-3 work to relate in any fashion to
the write-once device device type defined in SBC.

Current plan is to use the same device type code (i.e., 01h) for
sequential-access and indicate WORM capability via a device type
specific VPD page (see 04-178).

How does the proposed SSC-3 work relate to the Write-once device (e.g.,
some optical disks) device type defined in SBC and made obsolete in
SBC-2?

If this work is important, would it be more appropriate to revise the
SBC definition in SBC-2 instead of making the definition obsolete?

Please note that I am not at all thrilled by the idea of devoting two
scarce device type codes to a single device type.

All the best,

.Ralph
