ATOMM-II ultra-thin metal coating technology—
the key to compact size and high image quality
Introducing a complete line of DP Series products for conventional and digital HDTV broadcast use
DVCPRO is a high-efficiency digital component data-
compression recording system that uses a tape only 6.35mm
wide, making DVCPRO videocassettes the most compact
broadcast-use videocassettes in the world. For its DP Series
videocassettes, Fujifilm achieved the conflicting goals of
superior image quality and compact size by utilizing ATOMM-II*
technology to simultaneously apply an upper magnetic layer
and a lower non-magnetic layer to the tape base. Thanks to
ATOMM-II technology's ultra-thin upper layer of high-
performance magnetic particles, and its two-layer construction,

ATOMM-II Technology for
High-Density Digital Recording
Fujifilm's exclusive ATOMM technology is a special
coating process that simultaneously applies an ultra-thin
upper layer of high-energy metal magnetic particles and
a lower layer of ultra-fine non-magnetic particles.
Compared to the 2~5µm magnetic layer thickness of
conventional single-layer tapes, ATOMM technology
allows the creation of a high-density magnetic layer that
is only 0.1~0.5
µm thick. Thanks to ATOMM technology,
Fujifilm is able to create the ultra-thin magnetic layer that
is essential for high-density digital recording. For its DP
Series, Fujifilm uses ATOMM-II technology, a more
advanced form of the same technology. Featuring high-
performance magnetic particles and a magnetic layer
that is only 0.2
µm thick, ATOMM-II technology offers
high output, high C/N and a low error rate, providing
users with the dual benefits of high image quality and
compact size.

(25Mbps video recording rate) (100Mbps video recording rate)
Fujifilm was able to achieve previously unattainable recording
densities and a high level of reliability and durability. In addition,
Fujifilm has recently added high image quality, 4:2:2
compression ratio HDTV-compatible DVCPRO tapes to its DP
Series line-up. As a result, the Fujifilm DP Series now includes
tapes for broadcast-use applications ranging from conventional
to digital HDTV systems. In step with the rapid digitalization of
broadcast-use systems, Fujifilm's high standard of quality and
performance are now available to meet professional demands
on a complete range of DVCPRO systems
