An early non-volatile magnetic storage device. Developed by Bell Labs researcher Andrew Bobeck in the 1970s, bubble memory was about as fast as a slow hard disk but it held its content without power.

Going even further back in time [smbaker] is taking a look a bubble memory, a technology that was so fast and cost-effective for its time that it could have been used as “universal” memory ...

Abstract: Magnetic bubbles offer promise of data storage at a lower cost than is possible using semiconductor technologies. However, a memory using magnetic bubbles is most economically implemented in ...
