With special compaction using LZ1, the #6482 tape unit supports up to 8 GB. It may be used
for save/restore, Alternate IPL, program distribution, migration, and QIC tape exchange.
#6483 16 GB ¼-Inch Cartridge Tape Unit
The #6483 is not compatible with System/36 tape units.
The #6483 can be used for save/restore, Alternate IPL, program distribution, migration, and
¼-inch Cartridge tape exchange. Backward read capability to three previous generations of
QIC drives protects the customers investment in QIC technology.
Note that this tape contains different mounting parts when ordered for a 620, 720, or S20
model that supports tape concurrent maintenance, than when ordered for a 600 or S10 model
that does not support tape concurrent maintenance.
The #6483 provides 16 GB capacity native and 32 GB capacity compressed with a data
transfer rate of 1.5 MB/s (native) and 3 MB/s (with compression) using a 1500-foot cartridge
tape.
The #6483 provides 13 GB capacity native and 26 GB capacity compressed with a data
transfer rate of 1.5 MB/s (native) and 3 MB/s (with compression) using a 1200-foot cartridge
tape.
#6485 13 GB ¼-Inch Cartridge (QIC)
The #6485 is not compatible with System/36 tape units.
The #6485 provides 16 GB capacity native and 32 GB capacity compressed with a data
transfer rate of 1.5 MB/s (native) and 3 MB/s (with compression) using a 1500-foot cartridge
tape. The #6485 also provides 13 GB capacity native and 26 GB capacity compressed with a
data transfer rate of 1.5 MB/s (native) and 3 MB/s (with compression) using a 1200-foot
cartridge tape.
Tape tensioning control improvements in the tape unit eliminate the need for an
auto-retension pass during the data cartridge load sequence. This is a major time saving
since the auto-retension pass on earlier QIC tape units can take up to five minutes. The
#6485 Tape Unit retensions the data cartridge only when a loss of tension is detected. For
typical operating conditions, this is infrequent.
It may be used for save/restore, Alternate IPL, program distribution, migration, and QIC tape
exchange.
#6486 25 GB ¼-Inch Cartridge (QIC)
The #6486 is not compatible with System/36 tape units.
