This is a dead end.
Optical media doesn't write fast enough, nor does it have the necessary
capacity to warrant such a paradigm shift. I also suspect that they
won't hold up to field use (witness the CD player that skips when you
drive on a bumpy road beyond what the oversampling can compensate for).
Ultimately I think removable magnetic storage is the future for digital
video, but not until prices come down enough to compete with tape. That
alone may preclude this from ever happening. Tape is CHEAP. Lucas is
pushing hard for direct to HDD cameras. The HDD's need to be removable,
though. This is a MUST. You need to be able to change media quickly
during a shoot. There are also some environmental issues that need
addressing (i.e. it needs to be ruggedized).
