Pauli, WolfgangThe cartridges had a total capacity of up to 8.5 TB. They were actually manufactured by the Fujifilm company, used Barium Ferrite (BaFe) magnetic particle technology to store the user data and were equipped with a Radio-Frequency IDentification (RFID) chip (for quick access to the cartridge metadata).\ The tape length inside of each cartridge is 1147 meters while it is only 5.2 microns thick. Once mounted in a tape drive, the media moves over the drive head at the speeds of up to 4.7 meters/second when reading or writing, but up to 13 meters/second when locating to a file. Since 2019, all data that had been stored on such cartridges have been copied onto more modern supports. As of 2022, CERN uses similar tapes produced by other suppliers and having a capacity of up to 20 TB.
Oracle StorageTek T10000T2 cartridge has total capacity of 5 TB. It is actually manufactured by Fuji Film, uses Barium Ferrite (BaFe) particles technology data store, but is also equipped with RFID chip. There is over 1 km of tape inside of the cartridge with 3584 data tracks and it supports over 25000 load/unload cycles. The archival life is estimated to be around 30 years and uncorrected bit error rate is 10-19. CERN however usually migrates data to newer technologies roughly every 5 years in order to keep the footprint under control.
This data cartridge works on several StorageTek systems. The goal is to provide cartridge compatibility across several system. It has been designed for space saving and ultra-high capacity tape. It permit to fulfill high-volume backup, archiving, and disaster recovery.
A helical scan recording drive, with a high-speed rotating head sweeping across the tape every few micrometers. Based on a professional video recording system, modified to be suitable for digital data recording. These are commonly used with large computer systems, typically in conjunction with a robotic tape library.
It's a hand gripper assembly with camera for 9310.
