扫描探针显微镜(SPM)中使用的相互作用和驱动机制具有固有的存储应用潜力，但到目前为止，许多悬而未决的概念和技术问题阻碍了对这种潜力的彻底评估。然而，SPM仪器的固有性质和尖端/样品的相互作用允许估计一些重要的参数及其终值。应对并可能超过现有技术将需要SPM型记录磁头的大规模平行度，这一条件可以通过使用SPM型循环压电挠性致动器以一种优雅的方式满足。整个记录头阵列的操作将需要高度精密的微机械制造和/或复杂的控制机构。由此产生的公差要求可以通过选择远程SPM相互作用(库仑力、电容、近场光学等)来放宽。此外，交互必须允许高记录速度。对只读存储的限制可以促进探索性工作；这种情况下的写入过程可以被复制取代，类似于生产光盘中使用的技术。
Interaction and actuation mechanisms used in scanning probe microscopies (SPM) have inherent potential for storage applications, but many unresolved conceptual and technical questions have precluded a thorough assessment of this potential so far. However, the intrinsic properties of SPM instrumentation and tip/sample interactions allow a number of important parameters and their ultimate values to be estimated. Coping with and possibly surpassing established technologies will require massive parallelism of SPM-type recording heads, a condition that might be satisfied in an elegant manner by using SPM-type, circulating piezoelectric flexural actuators. Operation of an entire array of recording heads will require highly precise micromechanical manufacturing and/or sophisticated control mechanisms. The resulting tolerance requirement can be relaxed by choosing long-range SPM interactions (Coulomb forces, capacitance, near-field optics, etc.). Furthermore, the interaction must allow a high recording speed. The restriction to read-only storage can facilitate exploratory work; the writing process in this case might be replaced by replication, similar to the techniques used in the production of compact disks.
