The IBM TotalStorage Enterprise Tape Drive 3592 is designed to provide fast time to data and excellent levels of storage capacity. To support that high - capacity capability, the tape drive uses the IBM TotalStorage Enterprise Tape Cartridge 3592. The 3592 cartridge contains half - inch, advanced metal particle, dual - layer tape. This tape uses a high - quality coating that provides the signal and aerial density margin to store an extremely high capacity of data - up to 300GB (up to 900GB with 3: 1 compression), greatly exceeding the capacity available from most other tape media. The tape also features an ultra - smooth surface and uniform magnetic layer less than 0.2 microns thick - both intended to help improve media reliability and tape drive processing times. Because normal wear and tear can degrade media, the 3592 cartridge offers significant improvements in tape cartridge design - such as enhanced locking pin, hub and clutch assemblies - to help improve durability. The cartridge also minimizes surface defects and uses a precision timing - based servo formatting process to enable higher track densities without increasing error rates. With these design features, the 3592 tape cartridge can help better protect your mission - critical data.IBM 3592 Tape Cartridges are designed to work with the first - generation IBM TotalStorage Enterprise Tape Drive 3592 Model J1A (3592 J1A tape drive) and the second - generation IBM System Storage TS1120 Tape Drive (TS1120 Tape Drive).Cartridges are available in three lengths and in either re - writeable or Write Once, Read Many (WORM) formats. The short length 3592 JJ/JR cartridges provide rapid access to data and the standard length 3592 JA/JW cartridges provide high capacity. The 3592 Extended Data JB and Extended WORM JX 700GB high capacity cartridges support TS1120 tape drives only.
