A high storage capacity and density, lower cost when it is not being used it does not consume energy, and greater security against cyber attacks are some of the main reasons why tape storage technology, far from disappearing, is experiencing a new rebound thanks to cloud computing.

All the data that people worldwide and companies store on the cloud has to be backed up somehow. For a long time, the backup medium of choice has been magnetic tape, and IBM thinks that will continue to be true for decades to come. IBM says that the one technology able to handle the massive amount of data being created is magnetic tape, a 60-year-old technology.
IBM has announced a breakthrough in cooperation with Fujifilm to set a new world record for tape storage. The two companies are now able to achieve a storage capacity of 317 gigabytes per square inch. The massive capacity was reached on a prototype strontium ferrite particulate magnetic tape developed by Fujifilm.
Fujifilm’s massive 317 gigabytes per square inch capacity is 27 times more than the areal density in current state-of-the-art commercial tape drives. The new storage allows a single tape cartridge to store 580 terabytes of data. IBM puts the capacity in perspective, noting that 580 terabytes is equivalent to 786,977 CDs stacked 944 meters high.
Current generation magnetic tape uses barium ferrite particles on the magnetic tape storage media. Fujifilm went to the chemistry lab to invent the Strontium Ferrite particles used on the new tape providing superior properties with higher density storage for the same amount of tape. Along with new particles, new technologies were also developed to achieve the record, including a low-friction tape head.
The low friction tape head enables the use of very smooth tape media. A new detector to allow reliable data detection on the new media was created at a linear density of 702 Kbpi when the data is read back on a narrow 29 nm wide TMR read sensor. Fujifilm also created a new set of servo controllers that help maintain the precise position of the read/write heads relative to the tape using the head actuator. Those new servos enabled head positioning and accuracy of 3.2 nm, which is a world record.

Always thought there'd be more life to be had with tape by using different substrates. That's a colossal density!
It wisnae me! A big boy done it and ran away.
NVMe2G for life! until death (the end is nigh)
5 minutes of push-ups need 100MB storage (VP9 codec, three resolutions 360p 480p 720p).
580TB tape can store 55 years worth of push-ups.
If I do push-ups continuously for the rest of my life, I'll be able to fill up one of these tapes.
HostBrr aff best VPS.
We are impotent.
Please be kind, rewind.
The bad thing is, it offers slow access speed.

I like tape, just wish the drives weren't so expensive. You have to have an awful lot data before the cartridges + drives become equally cost effective to a pile of HDD's.
Well, these are archive only.
Means you dump your weekly incremental backups and if its full, you put that into storage.
You can only override it 200-400 times.
Sadly even for just backup data, to expensive, the fucking tape drive costs like 60$ or more a lone not to speak about the drive loader which is easy 100$+
