    • In an information processing apparatus which records and reproduces information by rotating a cylindrical recording medium on the basis of the principles of a scanning type tunnel microscope, the speed of the probe relative to that of the recording medium becomes fixed, and resonance and a decrease in an S/N ratio of reproduced signals during high-speed scanning can be prevented. Thus, information processing at a large capacity and high-speed response with a high degree of accuracy is made possible. An information processing system that records and reproduces information on the basis of the principles of a scanning type tunneling or an atomic force microscope employs a ferroelectric layer in the recording medium to simplify and improve reproduction. The recording medium may include a rotating cylindrical medium wherein the speed of the probe is fixed relative to that of the cylindrical medium to prevent resonance and to decrease the signal-to-noise ratio of reproduced signals during high speed scanning. Large capacity, accurate and high speed information processing is thereby obtained.
    • 在基于扫描型隧道显微镜的原理通过旋转圆筒形记录介质来记录和再现信息的信息处理设备中,探针相对于记录介质的速度变得固定,并且谐振和减小 可以防止在高速扫描期间的再现信号的S / N比。 因此,可以高精度地进行大容量的信息处理和高速响应。 基于扫描型隧道或原子力显微镜的原理来记录和再现信息的信息处理系统在记录介质中使用铁电层来简化和改进再现。 记录介质可以包括旋转的圆柱形介质,其中探针的速度相对于圆柱形介质的速度固定以防止共振并降低高速扫描期间再现信号的信噪比。 从而获得大容量,精确和高速的信息处理。
