Tandberg Data About Tape Streamers
2-8 Tandberg SLR Product Line SCSI Functional Specifications
„
A LOAD command is executed. This command always
brings the tape to the beginning of the default
partition (partition 0).
„
The cartridge is removed from the Drive. A newly
inserted cartridge must be loaded before it can be
accessed. The load operation positions the tape at
the beginning of the default partition (partition 0).
This will be true whether the load operation happens
as a result of an Auto Load or an explicit LOAD
command (with the Load bit set to one).
2.3.3. Using Initiator Defined Partitions
When using a SLRtape140 to SLRtape7 or SLR32, medium the
Initiator may specify both the number and the size of
partitions (the IDP bit is set to one).
The following table shows the minimum number of tracks
and track sets that can be allocated to a partition for
each medium type. It also shows the maximum number of
partitions and the minimum partition size.

Table 2-2: Minimum Partition Size
All partitions start at the BOT side of the medium. This
means that the Drive will be able to access any
partition with a minimum of tape movements after an
auto-load or a LOAD command.
