    • A micro-electro-mechanical systems (MEMS) device is presented that can read very high density magnetic media and very high density CD ROMs. Both the magnetic and optical read heads comprise one or more cold cathode MEMS e-beam cells. The e-beams are deflected according to the data bit being interrogated and the state of that bit is determined by a detector. Large arrays of such cells can simultaneously read large areas of the memory media. Arrays of such MEMs detectors can comprise a plurality of “steerable” e-beam emitters that can be directed to interrogate specific data sites on the magnetic media. Thus, in some cases, the media can remain stationary. Densities of 200 gigabits per square inch or more and read speeds greater than 1000 times faster can be achieved.
    • 提出了一种可以读取非常高密度的磁性介质和非常高密度的CD ROM的微电子机械系统(MEMS)装置。 磁读取头和光学读取头都包括一个或多个冷阴极MEMS电子束单元。 电子束根据询问的数据位而偏转,并且该位的状态由检测器确定。 这种单元的大阵列可以同时读取存储介质的大面积。 这样的MEM检测器的阵列可以包括多个“可转向”电子束发射器,其可以被引导以询问磁介质上的特定数据位置。 因此,在某些情况下,介质可以保持静止。 可以实现200吉比特每平方英寸或更高的读取速度,大于1000倍的读取速度。
