We have developed our own Filesystem for optical disks.
It currently runs with LMS-LaserDrives 1200 and correspondant
jukebox versions 1250.

It keeps the directory during work on the magnetic disk and puts
it at the end to the optical disk, so you can ship it or anything
else. This process can be done at any time, not only when the
cartridge is full.

There is a set of calls which are provided to use the OFS1200.
Despite the normal calls for working on files (o_open, o_close, read,
o_write, etc.) you have calls for mounting and dismounting of cartridges.
These calls take the directory from the optical disk and cache it
on the magnetic disk and vice versa.

For further information please contact me via email or
normal mail.
