IBM has regained the record for cramming data on a hard disk, using a new alloy to potentially triple the amount of available storage space.
IBM says it was able to squeeze 35.3 gigabits per square inch onto the hard drive, a 75 percent increase over the 20Gb level the company achieved less than five months ago.
At 35Gb density, every square inch of disk space could hold 4.375 gigabytes – enough for two full-length feature movies, or 77 hours of music.
The new data storage technique overtakes recent records set by Seagate Technology and Toshiba.
