185 TB tapes
Sony creó una cinta magnética con una densidad de almacenamiento de 148 Gb por pulgada cuadrada, con lo que un cassette actual que utilice esa cinta sería capaz de albergar hasta 185 TB de información, el equivalente a más de 300 computadoras portátiles comunes con un disco duro de 500GB, pero en un solo cassette.Para conseguirlo el nuevo tipo de cinta magnética Sony utilizó “deposición catódica, una tecnología para formar láminas delgadas al vacío, para generar múltiples capas de cristales con una orientación uniforme sobre un filme de polímero con un grosor de menos de 5 micrómetros”…
Sony has developed a new technology that pushes tape drives far beyond where they once were, leading to individual tapes with 185 terabytes of storage capacity.
Back in 2010, the standing record for how much data magnetic tape could store was 29.5GB per square inch. To compare, a standard dual-layer Blu-ray disc can hold 25GB per layer — this is why big budget, current-gen video games can clock in at around 40 or 50GB. That, however, is an entire disc, whereas magnetic tape could store more than half of that capacity in one little square inch. Sony has announced that it has developed a new magnetic tape material that demolishes the previous 29.5GB record, and can hold a whopping 148GB per square inch, making it the new record holder of storage density for the medium. If spooled into a cartridge, each tape could have a mind-boggling 185TB of storage. Again, to compare, that’s 3,700 dual-layer 50GB Blu-rays (a stack that would be 14.3 feet or 4.4 meters high, incidentally). In fact, one of these tapes would hold five more terabytes than a $9,305 hard drive storage array…
