When
the
drive
senses
a
WORM
cartridge,
the
firmware
prohibits
the
changing
or
altering
of
user
data
already
written
on
the
tape.
The
firmware
keeps
track
of
the
last
appendable
point
on
the
tape.

the
cartridge.
If

v
Inserting
a
WORM
tape
cartridge
into
a
drive
that
is
not
compatible
with
WORM
causes
the
cartridge
to
be
treated
as
an
unsupported
medium.
The

will
report
a

intervention.
Cleaning
Cartridge
A
specially
labeled
IBM
LTO
Ultrium
Cleaning
Cartridge
is
supplied
in
your
shipment
to
clean
the
drives
in
your
library.
The
drive
itself
determines
when
a
head
needs
to
be
cleaned
and
communicates
this
to
the
library.
When
the
cleaning
is
finished,
the
drive
ejects
the
cartridge
and
the
Picker
takes
the
cartridge
and
places
it
back
in
its
designated
cleaning
slot.
To
remove
a
cleaning
cartridge
from
its
designated
cleaning
slot,
export
it
from
the
library.
The
IBM
Cleaning
Cartridges
are
valid
for
50
uses.
The
cartridge’s
LTO-CM
chip
tracks
the
number
of
times
that
the
cartridge
is
used.
Cartridge
Memory
Chip
(LTO-CM)
All
generations
of
the
IBM
LTO
Ultrium
Data
Cartridges
include
a
Linear
Tape-Open
Cartridge
Memory
(LTO-CM)
chip
(
1
in
that
contains
information
about
the
cartridge
and
the
tape
(such
as
the
name
of
the
manufacturer
that
created
the
tape),
as
well
as
statistical
information
about
the
cartridge’s
use.
The
LTO-CM
enhances
the
efficiency
of
the
cartridge.
For
example,
the
LTO-CM
stores
the
end-of-data
location
which,
when
the
next
time
this
cartridge
is
inserted
and
the
Write
command
is
issued,
enables
the
drive
to
quickly
locate
the
next
available
recording
area
and
begin
recording.
The
LTO-CM
also
aids
in
determining
the
reliability
of
the
cartridge
by
storing
data
about
its
age,
how
many
times
it
has
been
loaded,
and
how
many
errors
it
has
accumulated.
Whenever
a
tape
cartridge
is
unloaded,
the
tape
drive
writes
any
pertinent
information
to
the
cartridge
memory.
The
storage
capacity
of
the
LTO-CM
is
4096
bytes.
