Advanced Technology Development in VLBI
 
                   ABSTRACT
 
 
The world of digital-data transfer and storage is changing rapidly and
will undoubtedly have profound effects on VLBI as well. We will examine the
current state-of-the-art in tapes, discs and high-speed data communications
to try to gaze into the future ways of moving VLBI data from station to
correlator.
Several Mark IV VLBI correlators are scheduled to come into operational
in mid-1999. We will discuss the structure of this international project,
design decisions, innovations and implementation. The power of this new
correlator system is crucial to the success of the upcoming CORE program,
as well as European and American VLBI astronomy programs.
