Time to throw out your mp3 player as Sony has unveiled a cassette tape with 185 TB of storage.

At the INTERMAG Europe 2014 – IEEE International Magnetics Conference in Dresden, Germany on Sunday, Sony unveiled a cassette tape that is capable of storing 148 GB of data per square inch of magnetic tape. This amounts to three Blu-rays worth of data per square inch, Gizmodo reports.

As an ExtremeTech article explains:

In order to create the new tape, Sony employed the use of sputter deposition, which creates layers of magnetic crystals by firing argon ions at a polymer film substrate. Combined with a soft magnetic under-layer, the magnetic particles measured in at just 7.7 nanometers on average, able to be closely packed together.

The article also points the previous record was set in 2010, with magnetic tapes capable of 29.5 GB of storage per square inch, but Sony’s new tape has a little more than five times the space.

To think of it another way, Exclaim.ca points out, the tape would allow you to store 8,093,750 days worth of music or 64,750,000 songs.

Of course, fast-forwarding to track 23,345,982 will likely be a real pain.

    The weak point of this would likely be the data retrieval and searching. It might be good for setting up long term archives, that would have a low likelihood of requiring frequent retrieval. That then asks the question if I likely never need the data is it worth recording it in the first place?

    To Tim Hodges … This is archival. System backup and recovery … duplicate systems and ghost systems means tons of redundant storage. This is a huge problem in surveilance where you have many camera’s, now HD, and with that many camera’s you need retreivable storage, maybe. You want to have the data after a robbery, but don’t look at it unless their is a robbery.

    Think that each minute with a 8 camera setup on HD can chew gigabytes, and this is a solution.
