The SDLT 600 tape drive system features a backward-read compatibility (BRC) mode. When in BRC mode, the SDLT 600 tape drive is capable of reading SDLT 220 and SDLT 320 tape formats in a Super DLTtape I data cartridge, as well as the DLT VS160 tape format in the DLTtape VS1 data cartridge.

Table 3-24lists the BRC transfer rates for the SDLT 600 tape drive.
