Tape Drive
There are several models of 3590s: standalone single drive, rackmounted with autoloader, etc.
The alpha character following the dash indicates what kind of read/write drive is used.
- 3590-B drive
- 128 tracks
- 3590-E drive
- 256 tracks
- 3590-H drive
- 384 tracks
Media
There are two kinds of 3590 media, distinguishable by the color of the plastic insert on the cartridge and the single letter designation.
- 3590-J media
- blue tab
- 1050 feet
- 3590-J tapes can be referred to as "3590" or "native" tapes, as they were the original length.
- 3590-K media
- green tab
- 2070 feet
- 3590-K tapes can be referred to as "3590E" tapes, as they are the "extended" length. This has nothing to do with the 3590-E drive model.
Capacity
The capacity of a given 3590 cartridge depends on the drive, the media, and compression.
It varies from 10GB to 180GB per cartridge.
| Drive | 3590-J media |
3590-K media |
|---|---|---|
| 3590-B | 10GB (30GB) |
20GB (60GB) |
| 3590-E | 20GB (60GB) |
40GB (120GB) |
| 3590-K | 30GB (90GB) |
60GB (180GB) |
- Note: (##GB) denotes capacity with compression.
