Fujifilm and IBM Set World Record With 580TB Magnetic Tapes
An anonymous reader quotes a report from PCMag.com: Mark Lantz, Manager of Advanced Tape Technologies at IBM Research, explains how researchers at IBM and Fujifilm brought together more than 15 years of work to set a new world record in tape storage. What they achieved is an areal density of 317Gbpsi (gigabits per square inch), which translates to a single tape capable of storing 580 terabytes of data. In order to achieve such a high areal density, the research team had to develop a brand new tape and created Strontium Ferrite (SrFe) in the process. Existing magnetic tapes rely on Barium Ferrite (BaFe), but SrFe offers the potential for higher density storage in the same amount of tape. Alongside that, the team also "developed a family of new servo-mechanical technologies including a new servo pattern that is pre-recorded in the servo tracks, a prototype head actuator and a set of servo controllers." The end result is a very high capacity tape that can be read while moving at a speed of 15km/h (9.3mph).
