New Record For Ferroelectric Recording Data Density

Researchers at Tohoku University have successfully stored 4 trillion bits per square inch, a record for ferroelectric data storage.  This is approximately eight times the  density of today’s magnetic hard drives. Researchers note that many improvements are needed before the project becomes commercially viable such as developing a low-cost ferroelectric substrate and increasing the speed and accuracy of read the data. However this project has the potential of replacing current storage systems. “We expect this ferroelectric data storage system to be a candidate to succeed magnetic hard disk drives or flash memory, at least in applications for which extremely high data density and small physical volume is required,” says Tohoku’s Yasuo Cho.
