Tandberg SLR Product Line SCSI Functional Specifications
2.8.2.1.
Using SLRtape140, SLRtape100, SLRtape75,
SLRtape60, SLRtape50, SLRtape40, SLRtape7,
SLR32 or SLRtape24 Media
When using SLRtape140 to SLRtape7 or SLR32 media it is
possible to compress data on any partition. It is also
possible to mix compressed and uncompressed data on the
same partition. This means that the state of the DCE bit
and the value of the Compression Algorithm field can be
changed any time during write operations.
The DDE (Data Decompression Enable) bit is ignored when
using these media. The Drive will, when transferring
data to the Initiator, always decompress compressed data
while uncompressed data are transferred without any
decompression.
2.8.2.2.
Using SLR5 or DC9250 Media
It is not possible to mix compressed and uncompressed
data on a SLR5 or a DC9250 media.
None of the drives covered by this manual are able to
write on these tapes. However, if the tapes are read,
the drives will automatically enable data decompression
if the tapes hold compressed data.
