_Hi8
(High
Eight)
Video
System
—
The
8
mm
video
system
employs
a
metal
powder
tape.
This
means
the
video
cassette
recorder
is
capabie
of
recording
a
large
amount
of
information
and
enhances
picture
quality.
The
Hi8
video
system
has
been
developed,
taking
advantage
of
the
8
mm
video
system.
The
main
characteristics
of
the
Hi8
are
as
follows:
“Super
High
Quality
Picture
:
The
information
capacity
is
a
key
element
for
picture
improvement.
It
can
be
increased
by
shifting
up
to
the
FM
carrier
frequency
range.
In
the
Hi8
video
system,
the
FM
carrier
frequency
range
of
the
luminance
signal
is
shifted
up
to
5.7—-7.7
MHz
This
is
higher
than
the
4.25.4
MHz
range
of
the
standard
8
mm
video
system.
Thanks
to
this,
the
horizontal
resolution
is
improved
to
more
than
400
lines.
Useé
of
High-Grade
Tape
Corresponding
to.
the
Hi8
Video
System
:
Metal
evaporated
tape
is
ideal
for
video
meena
because
it
has
large
magnetic
energy
that
allows
for
high-density
recording.
The
Hi8
video
cassette
recorder
uses
such
high-grade
tape
for
the
Hi8
video
system,
covering
a
wide
frequency
range,
to
achieve
a
high-quality
video
signal
for
recording/playback.
