Abstract
A tape cartridge for use in one or more tape drives of a tape library includes a cartridge housing and a magnetic tape. The magnetic tape is retained within the cartridge housing. The magnetic tape includes a first tape section that is pre-recorded with calibrated data for evaluating data durability on the magnetic tape. The magnetic tape is usable within the tape library to measure a health of the one or more tape drives and/or confirm a suitability of an operating environment within the tape library in terms of at least one of temperature and humidity. The calibrated data in the first tape section can be further configured for evaluating total transverse dimensional stability on the magnetic tape. The first tape section can include predetermined error patterns to assist in evaluating the data durability on the magnetic tape and/or periodic tape scrubbing operations to enhance data durability on the magnetic tape.
