Inspecting and Identifying a Cartridge

StorageTek Cartridges

The T9840 and T9940 Tape Drives use a cartridge tape that is the same physical size; however, they are not interchangeable.

The T10000 data cartridge can be used only in a T10000 tape drive, and the T10000 tape drive accepts no other type of cartridge.

T9840 Cartridge

The T9840 data cartridge has two reels between which the tape travels (FIGURE 5-1). It does not have a leader block. It cannot be used in a T9940 or LTO Ultrium tape drive.

The StorageTek 9840 cartridge tape was designed to provide fast access to data and storage of up to 20 gigabytes of uncompressed data with an average access time of just 12 seconds.

TABLE 5-1lists the specifications of the 9840 cartridge with the T9840x Tape Drives.
