I don't know alot about this technology, but...
Digital has a device and driver to read/write gapless on
BI based VAXes running VMS. The controller is the TM32, the driver
is PLDRIVER.
On the workstation side, you might contact the following outfit,
who I understand makes a QBUS gapless interfaces. I don't know if they
supply a UNIX driver, nor do I have their elephone number:
Duplication Technology

Good luck.
