EDM-9100B Overview
EDM-9100B-Sony 9.1 GB Optical is a Magneto-Optical (MO) data storage cartridge engineered for reliable, high-capacity data recording and archiving in professional computing environments. This re-writable optical media utilizes the 5.25-inch MO standard and delivers a native capacity of 9.1 GB per cartridge. As a rewritable optical disk, it is not categorized under tape formats like LTO, DLT, DDS, or AIT, and does not align with generations used in magnetic tape systems. The EDM-9100B is a standard data cartridge and is not available as a WORM (Write Once, Read Many) variant; encryption support is not implemented. The data transfer rate is determined by the drive, as MO media relies on optical disk drives rather than traditional tape interfaces.
With a specified archival life of up to 50 years, the Sony EDM-9100B is designed for enterprise backup, long-term data archiving, cold storage, and sectors requiring stringent regulatory compliance such as healthcare, legal, and financial institutions. Its robust media integrity and resistance to environmental factors make it suitable for critical applications where data longevity and security are paramount. The 5.25-inch optical cartridge is industry-standard for data libraries and jukeboxes, further supporting automated storage solutions. Tape length, transfer speed, and compatibility depend on the connected MO drive model, while the physical dimensions and weight support integration in data center environments.
