The '''IBM 3590
[[Image:3592Tape.JPG|thumb|right|3592 Series tape]]
All of these tape formats have half inch tape spooled onto 4-by-5-by-1 inch data cartridges containing a single reel. A takeup reel is embedded inside the tape drive. Because of their speed, reliability, durability and low media cost, the 3590 tape drives are still in high demand. A hallmark of the genre is transferability. Tapes recorded with one tape drive are generally readable on another drive, even if the tape drives were built by different manufacturers. Magstar tapes and drives are available in 128, 256 and 384-track versions. ▼

It is important to be aware that the tape is written at the drive's defined density and can only be read in a drive of the same model type or a higher version model.
So a tape written in the H drive can only be read in an H drive. A tape written in an E drive can be read in an E drive and an H drive. A tape written in a B drive can be read in a B, E or H drive.
Unlike DLT, LTO or 3592 drive variants, the 3590 drive is not capable of writing at a lower density than its native density.
There is often confusion in naming of the media and drives, the drives usually being referred to as 3590B, 3590E and 3590H. There are two types of media, the standard length media often being referred to as 3590 or 3590B, and the extended length media often being referred to as 3590E. Both types of media can be written in all three drives, the 3590E in the Ultra variant of the 3590B drive.
