I understand that Fujitsu might have been WORKING with the technology in 2006 but I think the report that they developed it is not correct. Seagate had been working on demoing the technology back in 2002 as reported in this article. —Preceding unsigned comment added by (talk) 21:23, 14 May 2010 (UTC)


Shouldn't Sony MiniDisc be mentioned in this article? Jeh (talk) 22:16, 17 August 2014 (UTC)

Energy usage.[edit]

If this thing is using heat to increase data density, doesn't that mean that the drive uses a lot of energy to produce that heat? How do the numbers compare with a non-hamr drive? I imagine this would be a bigger deal in enterprise server racks, where heat is already a huge problem. — Preceding unsigned comment added by (talk) 01:50, 23 December 2014 (UTC)

The lasers only need to heat a tiny area, so will use almost no power. [1] talks about a 150mW power usage laser, which is non-consequential compared to the ~5W total power usage of normal hard disks. Thue (talk) 04:01, 23 December 2014 (UTC)

Why not just optical ?[edit]

Once a laser is added, why not scrap the magnetic part and use light-only process ?

Of course they know what they are doing, but we don't so reasons should be explained. After all, it is similar to Magneto-optical drive that fell into disuse.Musaran (talk) 07:45, 21 July 2015 (UTC)

Impact on head design & performance ?[edit]

Since writing is now determined by the heating focus, this should remove heavy constraints on head design and allow some other improvements.
OTOH, the added weight is bound to slow head movements.

This should be covered. Musaran (talk) 07:50, 21 July 2015 (UTC)
