Figure 35. DDS Cartridge

Qualified DDS cartridges are designed with specific file protect, lid and other
features for information interchange and are tested to comply with the ANSI DDS
specifications.
The Scorpion 24 drive also recognizes all MRS cartridges when MRS is enabled.
MRS cartridges have a series of alternate opaque and clear stripes at the beginning
of the tape. These stripes classify the media as data grade, rather than audio-grade
media. Figure 36 points out the four recognition holes that allow the drive sensors to
identify the type of tape, its magnetic thickness and whether the tape is prerecorded,
unrecorded or is a cleaning cartridge. Other cartridge features allow the drive to
optically sense cartridge in, BOT and EOT.
