As a charter member of the Digital Data Storage Group (DDS), Maxell's 4mm data cartridges feature the Media Recognition System (MRS), which allows the drive sys-tem to detect the presence of data grade tape. Maxell uses only the finest quality magnetic media to meet the strictest specifications for a minimal dropout rate. Maxell then processes this media in a Class 10 clean room where it is certified for data recording purposes. To protect the fine metal particles in the magnetic layer of the tape, Maxell invented the ceramic coat-ing process. Maxell's ceramic coating acts as a protective armor against heat, humidity and eventual oxidation. The result is a tape durable enough to withstand at least 2, 000 passes with an archival life of up to 30 years. All Maxell 4mm data cartridges feature Maxell's unique Safe-T-Lock, a hub-locking mechanism that ensures proper tape tension and prevents mis-threading during the initial loading stage.
