Hitachi Predicts 3D Hard Disks by Year's End
daria42 writes "Hitachi has announced that its perpendicular, or 3D, hard disks should be out by the end of 2005." From the article: "Today, hard drives record and store data in a longitudinal fashion, with the read/write heads scanning over a horizontal plane. In perpendicular recording, data bits are aligned vertically, allowing for more data to be squeezed into a finite area. Put another way, data will go from being stored on a two-dimensional XY grid to living in a three-dimensional XYZ space."
How many whores can you fit in the Library of Congress? (By volume I mean).
Wish I'd patented it... Multi platter drives have been around almost as long as hard drives. I've always wondered (since the early 80's) how much faster a drive would be, if the data was written in "parallel" instead of "serial" (i.e. striped across 8 platters) I'm wondering, how on earth this "new" idea leads to claims that the data storage will be any denser.. a bit will still take up the same amount of physical space whether a byte's stored vertically ("3d") of horizontally so a platter would in theory not yield any more density than now?? Having said all that, I'm the proud owner of 20 IBM Deathstar drives^M^M^M^M^M^Mdoorstops, which are without a doubt the least reliable drives I've ever encountered. The very thought of putting any data on anything hitachi-IBM gives me the heebiejeebies...
