LTO
technology
is
an
“open
format”
technology,
which
means
that
its
users
have
multiple
sources
of
product
and
media.
The
“open”
nature
of
LTO
technology
enables
compatibility
between
different
vendors’
offerings
by
ensuring
that
vendors
comply
with
verification
standards.

local
area
network
(LAN).
A
computer
network
that
is
located
on
a
user’s
premises
within
a
limited
geographical
area.
The
network
consists
of
a
set
of
devices
that
are
connected
to
one
another
for
communication
and
that
can
be
connected
to
a
larger
network.
Communications
are
limited
to
a
moderate-sized
geographic
area
(1
to
10
km)
such
as
a
single
office
building,
warehouse,
or

In
fiber

technology,
the
amount
of
a

power
(expressed
in

that
is
lost

Low
Voltage
Differential
(LVD).
A
low-noise,
low-power,
and
low-amplitude
electrical
signaling
system
that
enables
data
communication
between
a
supported
server
and
the
drive.
LVD
signaling
uses
two
wires
to
drive
one
signal
over
copper
wire.
The
use
of
wire
pairs
reduces
electrical
noise
and
crosstalk.

LTO
Data
Compression
(LTO-DC).
A
method
that
compresses
a
server’s
data
before
the
drive
writes
it
to
tape.
LTO-DC
detects
but
does
not
recompress
or
test
record
boundaries
and
file
markers
(which
are
encoded
as
control
symbols).
It
also
allows
switching
between
compression
and
no
compression
within
the
data
stream,
which
prevents
data
from
expanding
when
the
drive
compresses
random
or
encrypted
data.
