'Racetrack' Memory Could Replace Hard Drives?
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."
It reminds me of bubble memory technology from the early 80's. Back then a Multi-bus card had whole 512K of non-volatile memory for an 8086. Later versions got larger but the ever increasing density of eeprom/flash and disk media doomed it.
