How long does LTO tape last?
The lifespan of data stored on LTO tape is usually quoted as 30 years. However, tape is extremely sensitive to storage conditions, and the life expectancy numbers cited by tape manufacturers assume ideal storage conditions -- a constant temperature of about 70 degrees Fahrenheit and 40% relative humidity.
Tape manufacturers usually quote the lifespan of their LTO tapes at about 30 years. However, LTO tapes are extremely sensitive to storage conditions, so this 30-year life expectancy assumes you are using ideal storage conditions - a constant temperature of about 70 degrees Fahrenheit and 40% relative humidity.
Cleaning tapes shouldn't expire because of date. The expiration is based on using up the cleaning media in the cartridge and is usually about 50 cleans. I checked back with the firmware team.
LTO Ultrium cleaning cartridges need to be replaced after 50 uses. The only time you must clean your Ultrium tape drive is when the tape drive alerts you to clean it.
Reuse the LTO tape
Reusing tape to store data can cut down the cost of storing data. Reusing the tape will also reduce the chances of data leaking.

To help organizations meet stringent compliance regulations, LTO technology includes a write-once, read-many (WORM) option (LTO-3 tapes and newer) that stores data in a non-rewritable format.
For quarter-inch tape drives, you should clean the head after every 8 hours of tape movement when using IBM tape cartridges. Other tape media might require cleaning more frequently. Clean the head on DAT tape drives after every 8 hours of tape movement when using IBM tape cartridges.
The LTO Cleaning Cartridge (known as the universal cleaning cartridge) and the LTO Cleaning Cartridge are compatible with all LTO tape drives.
This backward-compatibility was limited to read activities; write activities have always been restricted to one generation. In other words, an LTO-7 drive can read LTO-6 tapes and LTO-5 tapes, but the drive can only write to LTO-7 and LTO-6 tapes.
How does LTO cleaning tape work?
Cleaning consists of mounting a cleaning tape, which the drive winds over the heads and thereby the tape's surface binds and removes the debris off the heads. A cleaning tape can be used only for a certain number of cleaning cycles that is declared on its cover, before it looses its capacity to clean.
- Insert an Ultrium universal cleaning cartridge into the drive. The tape drive automatically loads the cartridge and cleans the heads. ...
- At the end of the cleaning cycle, the drive ejects the cartridge. The cleaning cycle can take up to 5 minutes.
- Remove the cleaning cartridge from the drive.
LTO-6 drives can read only LTO-4 media. If you are mixing LTO-4 with LTO-6 drives and media in a single library, you must mark the LTO-4 media as read-only. You must check out all LTO-4 scratch volumes. LTO-7 drives can read only LTO-5 media.
Tape-ins can be reused up to three times if removed and installed correctly, and although it's an easier method than some of the others, it's best to have a professional stylist install and move them up.
LTO-8 drives can read and write to LTO-7 tapes (note LTO-8 drives cannot read or write to LTO-6 tapes).
How is data encryption deployed on LTO tape? LTO Ultrium tape uses a symmetric encryption system. A single secret key, known only to the sender and receiver, is sent to the tape drive at the start of the backup operation. This key is used to encrypt (and subsequently decrypt) the data as it is written to tape.
Keep your tapes in a room without windows or shutter the windows to prevent excessive exposure. Contaminants - LTO tape is thin, with LTO 5 tape measuring only 6.4µm. As is the case with any thin magnetic media, contamination plays a major role in component decay and damage.
The most common method of destroying data on tapes is degaussing -- exposing the tape to a powerful magnetic field to scramble the data. If it's done properly, degaussing effectively destroys the data on tapes and allows reuse of tapes that don't have prewritten servo tracks.
LTO (Linear Tape-Open) tape is an open-format tape storage technology created by Hewlett-Packard (HP), International Business Machines (IBM) and Seagate Technology. The term open format means users have access to multiple sources of storage media products that are compatible.
LTO-9, the latest LTO magnetic tape standard was announced in the Fall of 2020. In the last few weeks the first LTO-9 products became available. LTO 9 tape has a raw capacity of 18TB and compressed storage capacity at 2.5:1 of 45TB (50% more than the prior generation LTO-8 product).
Who manufactures LTO tapes?
As of 2019, only Fujifilm and Sony continue to manufacture current LTO media. Compliance-verified licensed manufacturers of LTO technology media at one time were EMTEC, Imation, Fujifilm, Maxell, TDK, and Sony. All other brands of media are manufactured by these companies under contract.
This product is Write Once Read Many (WORM). Once written to it cannot be written over. WORM allows non-rewriteable and non-erasable data to be written, and provides extra data security by prohibiting accidental data erasure.
For quarter-inch tape drives, you should clean the head after every 8 hours of tape movement when using IBM tape cartridges. Other tape media might require cleaning more frequently. Clean the head on DAT tape drives after every 8 hours of tape movement when using IBM tape cartridges.
LTO-8 offers a compressed storage capacity of 30TB (12TB native) using a 2.5:1 ratio, and a compressed transfer rate of 750 MB/sec. (360MB/sec. native). In addition, the new LTO-8 drives are backward compatible with LTO-7 tape media, allowing users to read/write any LTO-7 media.
LTO-6 drives can read only LTO-4 media. If you are mixing LTO-4 with LTO-6 drives and media in a single library, you must mark the LTO-4 media as read-only. You must check out all LTO-4 scratch volumes. LTO-7 drives can read only LTO-5 media.
The LTO cartridge has a single reel of tape. When in the tape drive, the tape gets wound into the drive to the take-up reel. Tape length started with 600m and is now at 960m per cartridge. Capacity usually doubles from one generation to the next and now is at 12TB native.
