info on WORM filesystems

[Dave Wilson]

I have a Sperry 51C Write-Once-Read-Many(WORM) optical disk
drive that I am evaluating. The intended use is as an archival
media to replace magnetic tapes and floppy disks for long-term
storage of computer generated data. The drive comes with an interface
card for an IBM-PC, an MS-DOS device driver and a set of utility programs.

A SCSI interfaced drive is also available, but the media is not compatible
with the PC-based version, and no software support is available yet.

I am interested in any filesystem format standards (in any stage of progress)
that address WORM media physical formats & operational characteristics.
I have looked into Compact-Disk Read-Only-Memory(CD ROM) standards,
and they are tied too closely with the physical format & operational
characteristics of compact disks, which have already been standardized.

The goal of my efforts is to provided an filesystem format on WORM media
that can be used with PC's, mini's and mainframe systems, with different
operating systems(MS-DOS, Xenix, Unix, VMS, Cyber NOS/BE...).
