Medium Auxiliary Memory

Medium Auxiliary Memory (MAM) is a feature in the SDLT 600 tape drive that produces various
attributes about the data cartridge and records them in a log file on the media itself. These attributes
provide the underlying information for the DLTSage suite of predictive and preventive maintenance
diagnostics software.

For more information about MAM, see the SDLT 600 SCSI Interface Guide (81-81200-01) or the
SDLT 600 Fibre Channel Interface Guide (81-81202-01). For more information about DLTSage, see
the DLTSage Implementation Guide (81-81201-01).
