    • A method used in an access module that uses a file system to manage a nonvolatile memory of an information recording module enables an available storage space to be calculated in a short time before file data is recorded, and shortens the time required from initialization of the file system to recording. An access module (1) manages information about area management of the file system configured in an information recording module in units of fixed-length blocks. A divisional available storage space calculation unit (103) performs an available storage space calculation process in units of the fixed-length blocks, and completes preparations for recording when detecting a minimum required storage space for recording file data and enables recording of the file data. This shortens the time required from initialization of the file system to recording.
    • 在使用文件系统管理信息记录模块的非易失性存储器的访问模块中使用的方法使得能够在文件数据被记录之前的短时间内计算可用存储空间,并且缩短文件初始化所需的时间 系统录音。 访问模块(1)以固定长度块为单位管理在信息记录模块中配置的文件系统的区域管理的信息。 分割可用存储空间计算单元(103)以固定长度块为单位执行可用存储空间计算处理,并且在检测用于记录文件数据的最小所需存储空间并完成文件数据的记录时,完成记录准备。 这缩短了从文件系统初始化到录制所需的时间。

    • A scanning probe microscope for scanning a probe needle in proximity to a surface of a sample in XY-axis directions while moving at least one of the probe and the sample in a Z-axis direction has a plurality of band-pass filters for passing a plurality of band-pass signals by extracting predetermined frequency bands different one another from a surface geometry signal output by a probe. An image memory stores the respective band-pass signals and corresponding positions on the sample surface, and a color image outputting device outputs a color image by treating each of the respective band-pass signals stored as image data in the image memory as different color data and combining the data. The plurality of band-pass signals includes a first band-pass signal having a first frequency range set to include only abrupt transitions in the sample surface and a second band-pass signal having a second frequency range set to include frequencies slightly outside the first frequency range so that abrupt transitions in geometry on the sample surface are represented by a first color in response to the first band-pass signal and areas directly adjacent the abrupt transitions on the sample surface are represented by a second color different from the first color.
    • 扫描探针显微镜,用于在沿Z轴方向移动探头和样本中的至少一个的同时沿XY轴方向扫描样品表面附近的探针,具有多个带通滤波器,用于使 通过从由探针输出的表面几何信号中提取彼此不同的预定频带,来产生多个带通信号。 图像存储器将各个带通信号和相应的位置存储在样本表面上,并且彩色图像输出装置通过将作为图像数据存储的各个带通信号中的每一个作为不同的颜色数据进行处理来输出彩色图像 并组合数据。 多个带通信号包括具有第一频率范围的第一带通信号,其中第一频率范围被设置为仅包括采样表面中的突变,以及具有第二频率范围的第二带通信号,第二频带设置为包括稍微在第一频率之外的频率 范围,使得样品表面上的几何形状的突变过渡由第一颜色响应于第一带通信号表示,并且与样品表面上的突然跃迁直接相邻的区域由不同于第一颜色的第二颜色表示。
