Ph.d. Candidate Optimizes New Data Storage Method
The parallel probe-based data storage technique uses the same principle as a record-player, whereby a needle moves across a disc and reads the structure.

The University of Twente's Johan Engelen has optimized a new storage technique by adding another motor, which which drives a needle that reads bits. The new technique, dubbed parallel probe-based data storage, works similarly to a record player by moving the needle across a disk. The technique was improved by using a more energy-efficient motor, a comb drive.
"Flash memory works with threads criss-crossing over each other to form a mesh, with a bit at every crossroads. The more bits, the larger the memory," Engelen says. "During my research, I examined a new technique, which does not work with a mesh, but with a needle that reads the bits."
The new storage method uses a relatively large amount of energy, so the researcher implemented a different motor, a comb drive. The motor works using 10 times less energy, and more energy remains during the movement to steer the needles. "The new technique is not yet ready to be marketed," Engelen says. "Existing techniques are still so cheap and offer so much scope for expansion that we won't be ready for new techniques for another 10 years."
