Tape Requirements
The MiniLibrary system uses ECMA-approved, ANSI proposed-standard DLT
tape cartridges. The DLT tape cartridge is a four-inch square plastic cartridge.
DLT tapes are available in three types, each with varying length and capacity,
as listed in Table 2-11.

Cartridge Handling and Storage
A DLT tape cartridge should be stored vertically until you want to use it. Do
not expose a cartridge to moisture or direct sunlight. Maintain a clean,
dust-free working and storage environment.
If a DLT tape cartridge is dropped:

System magazine or any drive.
■

rattling sound makes a cartridge unfit for use.
■
Inspect the case for distortion or cracks.
■

(see Table 2-12). The leader should be positioned as shown in view 1,
and should protrude at about a five-degree angle from the case. If the
leader is out of position, do not use the cartridge; damage to the drive
could result.
Under certain conditions, a DLT tape might stick to the drive read/write head
during operation. Damage to media, failure of commands or batch jobs to
