'Racetrack' Memory Could Replace Hard Drives? 149
Galactic_grub writes "An experimental new type of memory that uses nanosecond pulses of electric current to push magnetic regions along a wire could dramatically boost the capacity, speed and reliability of storage devices. Magnetic domains are moved along a wire by pulses of polarized current, and their location is read by fixed sensors arranged along the wire. Previous experiments have been disappointing, but now researchers have found that super-fast pulses of electricity prevent the domains from being obstructed by imperfections in the crystal."

Well, actually it's worse than the stone age. Back then we had "Monoliths" which (apart from glacial shift and other geological "features" - or "bugs" as anyone outside sales management called them) had no moving (of movable even) parts at all.
When the storage space on a monolith wasn't enough you could expand to a "Circle".
Still, the space on a full circle even with a connected "Altar" and a full set of "Druids" and "Maidens" peripheals wasn't more than perhaps 256 bytes. So the monolith system was later on replaced by paper which had the benefit of portability but the drawback of reduced lifespan.
Paper was a very popular form of storage, though with some flaws. For example attempts at "burning" information onto papers were done several times in recorded history (for instance back in 1939) but even if it was a fast and effective way to handle the information it was totally destructive to the media and had to be abandoned. Burning then lay dormant as a form of inprinting information on media until the discovery of CD's.
CD's are a hybrid technology combining one not very moving part with several moving parts that moves the unmoving part around. No clever explanation for this behaviour has ever been found and most scientists just doesn't like to talk about it.

One day, when the first protoype of the DHU-11 (we're talking wire-wrap here) was to be demoed, he rigged up a little plastic pipe that ran from the backplane of the PDP 11/24 holding the prototype to a place just out of sight of the various higher-up mucky-mucks who were receiving the demo.
Right after the machine was fired up, he took a big drag on his cigarette and blew into the pipe. Smoke out of backplance, widespread panic in lab. I mean, we all know that ICs become useless after the magic smoke is released, and we were using some of the first 8751s Intel ever made.
After we staked him out over an ant hill, we went off for pints at the Swan at Streatley.
