Error Checking

Drives used in the MiniLibrary system apply a 16-bit parity check to each
record, a 64-bit CRC to each 4 KB of data, and Reed-Solomon error correction
code overall. There is also an internal parity check on the data buffer.

Compression

MiniLibrary system drives use the standard Digital Lempel-Ziv (DLZ) data
compression algorithm.

Capacity

A single Base Module with its 10-cartridge magazine offers formatted
capacities as listed in Table 1-8. The data capacities of an Expansion Unit and
a Data Unit are listed in Table 1-9. The capacity of any module is determined
by the series of drive used, as well as the media type. When DLTtape III,
IIIXT, or IV cartridges are used with DLT4000, DLT7000, or DLT8000 series
drives, capacities are limited accordingly.
