Handling the Tape Drive
! Do not carry the tape drive by inserting your fingers into
the receiver area. You could damage the tape drive if you
lift or carry it in this manner.
Do not stand the tape drive on its front panel.
Always place the tape drive on a flat, stable surface.
Avoid dusty, humid, or smoke-filled areas.
Use proper Electrostatic Discharge (ESD) protection.
Allow at least 6 inches of space behind the drive for
ventilation.
Handling Data Cartridges
Protect cartridges from shock, vibration, moisture, direct
sunlight, dust, smoke, and magnetic fields.
Use the slide-in labels provided. Do not use adhesive
labels or Post-it® notes, and do not write on the cartridge.
Never touch the tape or tape leader. Dust and oils from
your skin contaminate the tape and affect performance.
Keep cartridges in their protective cases when not in use.
Store data cartridges vertically.
! Always visually inspect a data cartridge before placing it
in the tape drive. If it is damaged, do not use the cartridge.
B4
! Never power off the tape drive while it contains a
cartridge.

Over time, ambient pollution and particulates in the
environment contaminate the tape heads. The tape drive
indicates when cleaning is required by illuminating the
yellow Cleaning Required LED. A2
! Do not clean the tape heads unless the Cleaning Required
LED is illuminated.
! Use ONLY the SDLT CleaningTape. Other cleaning tapes,
such as CleaningTape III or DLT VS CleaningTape, are
incompatible with the SDLT 220/320 tape drive heads.
To Clean the Tape Heads
1. Insert a Super DLTtape cleaning cartridge (the brand name
to look for is SDLTtape™ CleaningTape) into the tape
drive.
The green Drive Status LED flashes and the cleaning cycle
begins automatically.
When the cleaning cycle completes, the tape drive
automatically ejects the CleaningTape; turns off the Cleaning
Required LED; and steadily illuminates the Drive Status
LED.
2. Remove the CleaningTape, place it back in its plastic case,
and mark the label after each cleaning.
Note: On the last cleaning, the tape drive does not eject the
CleaningTape. Use the Eject button on the front of the
tape drive to eject the expired cleaning cartridge and
dispose of it.
B1 | Super DLTtape Media
B Using Data Cartridges
B1 Super DLTtape Media
From the outside, the Super DLTtape I cartridge looks very
similar to the DLTtape IV cartridges. The basic geometry,
write-protect switch, and label space are unchanged from the
DLTtape IV cartridge. This simplifies the integration of
Super DLTtape into existing operating environments and
into automated tape libraries.
The Super DLTtape I cartridge is easy to recognize; it has
a different color (green) than the DLTtape IV cartridge
(charcoal gray) and contains a distinctive pattern molded
into the shell. The Super DLTtape I cartridge has a keying
feature to ensure that it cannot be loaded into previous
generation DLTtape drives.
Both the SDLT 220 and SDLT 320 tape drives feature an
optional backward-read compatibility (BRC) mode. When in
BRC mode, the drives are capable of reading DLTtape IV
tapes with DLT 4000, DLT 7000, DLT 8000, and DLT 1
formats. The Backward-Read Compatibility table below lists
BRC rates for the Super DLTtape drive.
Backward-Read Compatibility
Format Cartridge Type Native Capacity (GB)
SDLT 320 SDLT I 160 16.0
SDLT 220 SDLT I 110 11.0
DLT 8000 DLT IV 40 4.0
DLT 7000 DLT IV 35 3.5
DLT 4000 DLT IV 20 1.5
DLT 1 (Benchmark) DLT IV 40 3.0
Notes:
• Transfer rates quoted are nominal, measured reading uncompressed data.
• Non-SDLT drives will eject a cartridge written in SDLT 320 format.
• The SDLT 320 can read and write the SDLT 220 format at the native SDLT 220 transfer rate of
11.0 MB/s.
