Magnetic storage using lasers alone

Posted on February 9, 2012 by Ray

Read an article today on AAAS Science Now online magazine (See Hot Idea for a Faster Hard Drive) on using lasers alone to toggle magnetic moments in specially designed ferro-magnetic materials. The disk industry has been experimenting with bit patterned … Continue reading →

Disk drive density multiplying by 6X

Posted on October 18, 2011 by Ray

In a news story out of Singapore Institute of Materials Research and Engineering (IMRE), Dr. Joel Yang has demonstrated 6X the current density on disk platter media, or up to 3.3 Terabits /square inch (Tb/sqin). And it all happens due … Continue reading →

Disk trends, revisited

Posted on October 5, 2011 by Ray

An interesting guest post on Claus’s Blog (Claus Mikkelsen of HDS) by Ian Vogelesang of HGST provided some technical/economic insights on why specific disk drives are more economically feasible than others. It’s a bit hard going and more technical than a … Continue reading →

Sequential only disk?!

Posted on April 13, 2010 by Ray

Was at a Rocky Mountain Magnetics (IEEE) seminar a couple of weeks ago and a fellow from HDS GST was discussing recent advances in bit patterned media (BPM).  They had shown some success at 45nm by 45 nm bit cells … Continue reading →
