Coinciding beautifully with the ongoing battle we have with nostalgia, Sony has announced a reworking of the cassette that could bring it back from the dead. Their latest tape can hold up to 148 GB's per square inch, e.g., up to 64,750,000 songs (to serve as comparison, regular cassette tapes released in 2010 could only store about 30GB).

The tape was unveiled last weekend at the International Magnetics Conference in Dresden, and its astonishing storage capacity is made possible, according to Gizmodo, via a "vacuum-forming technique called sputter deposition to create a layer of magnetic crystals by shooting argon ions at a polymer film substrate. The crystals, measuring just 7.7 nanometers on average, pack together more densely than any other previous method."

Although the tape was developed for "long-term, industrial-sized data backup," it is expected to be available for sale (a release date has yet to be unveiled).
