Sony announced a couple days ago that the company developed a new magnetic tapetechnology with the world's highest areal recording density of 148 Gb per square inch. This recording density is equivalent to approximately 74 times the capacity of current mainstream coated magnetic tape storage media, and makes it possible to record more than 185 TB of data per data cartridge.
A cassette tape with 185TB sounds cool, but of course is only interesting for storage facilities and not for consumer purposes.
Sony has developed a new vacuum thin film forming technology which is able to form extremely fine crystal particles with the aim of creating a practical, next generation tape storage media. This newly developed magnetic tape technology uses sputter deposition, a type of vacuum thin film forming technology, to generate multiple layers of crystals with a uniform orientation on a polymer film with thickness of less than 5 micrometers.
Sony will continue to work towards commercializing this next generation tape storage media, as well as the development of increasingly advanced thin layer deposition technologies based on the sputter method, with the aim of increasing recording densities even further.
The compact cassette tape was invented by Philips and unveiled at the Berlin Radio Show in 1963. It stayed with us until the 90s when the CDs took over.

The “geek mind” is concerned with more than just the latest iPhone rumors, or which company will win the gaming console wars. I4U is concerned with more than just the latest photo shoot or other celebrity gossip.
The “geek mind” is concerned with life, in all its different forms and facets. The geek mind wants to know about societal and financial issues, both abroad and at home. If a Fortune 500 decides to raise their minimum wage, or any high priority news, the geek mind wants to know. The geek mind wants to know the top teams in the National Football League, or who’s likely to win the NBA Finals this coming year. The geek mind wants to know who the hottest new models are, or whether the newest blockbuster movie is worth seeing. The geek mind wants to know. The geek mind wants—needs—knowledge.
