Hard Disk Idea

I just thought of building a novel Hard disk with no moving components at all!

Each platter will have another platter on top of it with an circular-array of heads mounted on it. So now, nothing moves! The heads are only electronically switched on and off to read from or write to the disk. Wouldn't it be a fantastic and elegant solution? No more head crash and no more motors! This translates to a very reliable system and a low powered one too. Caching becomes far easier and scheduling algorithms like SCAN and C-SCAN are not required (some others will be required in its place, though).

Of course holding the entire platter of heads just above the magnetic platter is very difficult, but now we can actually support the head platter at the landing zone.

I would like to hear from my readers about this idea.
