磁扭线存储器（英语：Twistor memory）是一种计算机存储设备，类似磁芯内存，通过包裹或封闭通电导线附近的磁带来实现。尽管磁扭线存储器的开发者贝尔实验室对它抱有很大的希望，它只在1968年到1970年中旬很短的一段时间里得到市场应用。这段时间里，早期的存储接介质都很快地被拥有更高访问速度、更低生产成本的半导体存储芯片取代。磁扭线存储器主要源于Andrew H. Bobeck的个人想法。不久之后，它总结了磁扭线存储器的一些概念，研发了磁泡存储器。

Twistor is a form of computer memory formed by wrapping magnetic tape around a current-carrying wire. Operationally, twistor was very similar to core memory. Twistor could also be used to make ROM memories, including a re-programmable form known as piggyback twistor. Both forms were able to be manufactured using automated processes, which was expected to lead to much lower production costs than core-based systems.
