I sold write-once filesystem software to optical mass storage and jukebox manufacturers on the West coast such as Phillips/LMSI, Canon, Sony, Fujitsu, Maxtor, Cygnet, Filenet, Hitachi, IBM and HP. My account Cygnet was a subcontractor to Ford Aerospace for the data storage and retrieval system for the Hubble Space Telescope project.
NHance systems marketed "WOFS" (write-once-file-system), the result of research by Simson Garfinkel while he was at MIT's Media Lab. WOFS was designed specifically for managing the difficult problem of how to read and write data to a disk that doesn't allow erasures. Data stored on "write -once" optical storage media is known as WORM - write once read many.
We also sold a software product called Curator, which managed files on the write-once disk. A truly great product that would literally take a user backward and forward in time, an offshoot of version control software. It was written by Al Polans.
Unfortunately faulty mirrors in the Hubble telescope put an end to the entire data storage and retrieval project. Soon after, NHance folded.
Simson was subsequently hired by Steve Jobs to work on the CD-ROM filesystem software for the NeXT machine, which was originally sold without a hard drive, just a magneto-optical drive from Canon. Doh! Two years later, Jobs sold the machines with hard disks CD-ROM drive.
NeXT was sold to Apple in 1996. The OS became a significant part of the OS X operating system which I'm using now to write this. It's possible that WOFS is part of the OS X CD/DVD ROM burning software.
