Scorpion 240 Product Manual

Qualified DDS cartridges are designed with specific write-protect, lid and other

features for information interchange and are tested to comply with the ANSI DDS

specifications.

The Scorpion 240 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 20 shows 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

determine the cartridge in, BOT and EOT points.

The cartridge also provides for write protection so that existing data on the cartridge

is not overwritten (See Figure 21). A write-protected cartridge allows the existing

data to be read but does not allow new data to be written to the tape.

Note. A write-protected cartridge

prevents the error log (in the

system area) from being

updated.
