System Description 1-15 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.
