Occasional Cleaning of Tape Head
SDLT uses a built-in tape cleaning algorithm in conjunction with a cleaning tape.
The SDLT cleaning tape is housed in a plastic case, and is light gray in color.
Cleaning cartridges expire after 20 cleaning cycles.
A yellow LED (light) located on the front bezel of the tape drive indicates when
cleaning is needed; the location of this LED (and other front bezel LEDs) is shown
in
Figure 2-7 on page 2-26
.
N
OTE
: The tape cleaning algorithm is not used for the BRC
(backward read compatible) head; this head style does not
need cleaning.
2.9.1 Load Time for Cleaning Cartridge
Load (cycle) times for SDLT cleaning cartridges are as follows; these times are
accurate ± 20 seconds:
Shortest load time (1st pass of cleaning cartridge): 2 min. 55 sec.
Longest load time (20th pass of cleaning cartridge): 10 min. 20 sec.
“Expired” load time (expired cleaning tape): 4 min. 30 sec.
On the last pass, the cleaning process stops, the tape is rewound, but the cartridge
is not ejected. If the tape is loaded again after the 20th pass, it winds all the way to
the end of the cartridge and back again without performing the cleaning sequence;
the tape does not eject.
C
AUTION
: Never use a DLT cleaning tape in an SDLT drive; DLT
cleaning tapes are incompatible with the SDLT heads.
