Magnetic Tape Data Storage Breakthrough Will Make Your Hard Drive Seem Tiny

http://gizmodo.com/magnetic-tape-data-storage-breakthrough-will-make-your-1797462392
The amount of data you can squeeze onto a hard drive continues to grow by leaps and bounds, with Seagate announcing a 60TB SSD late last year. But thanks to IBM and Sony, tape might still reign supreme when you need to archive massive amounts of data, as the companies have jointly developed a new kind of tape that can reportedly hold 201-gigabits, or roughly 25GB, per square inch.
...
IBM’s researchers developed a new read head just 48-nanometers in size that was capable of accurately reading the minuscule magnetic particles on Sony’s new tape, as well as new servo technology allowing for precise control of the tape as it flows through the machine. Accuracy and precision have to be improved as the magnetic particles holding the data get smaller and smaller.

  • No thanks on tape drives. Every one that I have had over the last 20 years would not read a tape after 5 years.

  • The tape drives used on mainframes are very much superior to the ones used on PCs.

    But 200GB is not much these days, what with 3.5" 1TB USB 3.0 HDD for <$50.

    Most laptops these days have ~1TB HDDs. That's 5 tapes to backup the whole HDD !
    When it comes to backing up a server, it's going to require a lot of tapes!

  • According to the article:

    That's 25 GB per square inch!

    or 301 TB on a kilometer of tape.

    100's of terabytes (TB) of storage, not gigabytes.
    But when you fill a cartridge with over a kilometer of this new tape, you can store 330TB of data in less space than a hard drive takes up.

    No thanks, had the cassette type a couple of times. Can't seem to find the cartridge system I had in the 90s, way too slow for today's data.
