Cartridges
Currently, there are two types of 9840 tape cartridges ( Figure 1-15 on
page 1-17 ). Customers may purchase the standard and the VolSafe cartridge.
• The standard cartridge uses white labels and can be write protected. If not
write protected, data can be written over. Refer to
Table 1-4 .
• The VolSafe cartridge uses yellow labels and cannot be written over. Data
can only be appended to the information on the cartridge. Refer to
Table 1-4 .
The cartridges have one supply and one take-up reel. The design allows for
mid-point loading and provides an average access-to-data time of 11 seconds.
The dual-hub architecture yields a load/initialize time of 4 seconds.
The 9840 Tape Drive cartridges have the same dimensions as the 18- and 36-
track tape drive cartridges. This allows mixing of cartridges within existing
libraries.
Note: See Cartridge Specifications in Appendix A, “Specifications,” for more
specific information.
Do not use a VolSafe tape to make a dump, code, data tape, or to build
an MIR. A “
Write Prot ” message displays if a VolSafe tape is used.
Table 1-4 shows the similarities of the standard and VolSafe cartridges.
