Dataslide expanded (Score 1)

My understanding is that the oscilating sheet is very stiff glass-like material with storage lements (like pixels in a way) layered onto it in a photo-lithography process. Above it, and potentially below it, is an array of read:write heads that are fixed whilst the glass sheet vibrates through pizeo-electronics. The read:write heads are made from standard LCD fabrication techniques. The prototype uses less than 4% of the power needs of a rotating hard drive. The glass sheet has a zero co-efficient of expansion. The data addressing is direct addressing in 512 byte page segments, on standard magnetic media. The prototype has a HDD-equivalent speed of 72,000 rpm with potential to reach 12 million rpm. (Should be opm really - oscillations per minute?) It's all early days with 3 years needed, I guess, for product to appear. Neat idea though.
