PLENTY OF MEMORY AT THIS TIME

Seagate can now put a trillion bits of data on one square inch of a disk drive. They will soon come out with a six terabyte 3.5-inch drive for desktops and a two terabyte 2.5-inch drive for laptops. A 60 terabyte drive is feasible, say the engineers. To put that in perspective, a 60 terabyte drive could hold 216 million pages of text or 18,000 hours of good-quality video.

Seagate claims it is achieving this density through “heat assisted magnetic recording” (HAMR).  HAMR gets around the problem that occurs from packing data too tightly on a magnetic surface. Normally, the data gets corrupted as it magnetizes, but with HAMR, the bits are more resistant.

  1. Dear Joy & Bob,
    I have been a faithful weekly reader of On Computing for years.
    I’ve learned more from you two than any of the hundreds of computing books I own. You two, in short, and not only wonderful but completely accessible. Thank you for all the great columns over all the years.
