摘要： A structure having a thin film magnetic layer sandwiched between a substrate and a surface layer is bombarded with ions. The ions impact the surface layer and cause atoms from the surface layer to be moved to implant into the magnetic layer. Thereby the magnetic characteristics of a region of the magnetic layer are altered, modified or destroyed.

摘要： An article identification method can comprise: determining a signature from an article based upon an intrinsic characteristic of the article; and comparing the determined signature to a stored signature. The method can also comprise splitting the determined signature into blocks of contiguous data, performing a comparison operation between each block and respective blocks of the stored signature, and comparing an attribute of a comparison result from each block comparison to an expected attribute of the block comparison to determine a compensation value for use in determining a comparison result. The method can also comprise determining a similarity result between the determined signature and the stored signature, using the compensation value to adjust the determined signature. Thus an article damaged by stretching or shrinking can be successfully identified. Also, a non-linear signature determination can be accommodated without losing identification accuracy.
摘要翻译：物品识别方法可以包括：基于物品的固有特征来确定物品的签名; 以及将确定的签名与存储的签名进行比较。该方法还可以包括将所确定的签名拆分为连续数据块，执行每个块和存储的签名的相应块之间的比较操作，以及将来自每个块比较的比较结果的属性与块比较的预期属性进行比较以确定用于确定比较结果的补偿值。该方法还可以包括使用补偿值来确定确定的签名和存储的签名之间的相似性结果，以调整所确定的签名。因此，可以成功地识别被拉伸或收缩损坏的物品。此外，可以适应非线性签名确定而不失去识别精度。

摘要： A digital signature is obtained by digitising a set of data points obtained by scanning a coherent beam over a paper, cardboard or other article, and measuring the scatter. A thumbnail digital signature is also determined by digitising an amplitude spectrum of a Fourier transform of the set of data points. A database of digital signatures and their thumbnails can thus be built up. The authenticity of an article can later be verified by re-scanning the article to determine its digital signature and thumbnail, and then searching the database for a match. Searching is done on the basis of the Fourier transform thumbnail to improve search speed. Speed is improved, since, in a pseudo-random bit sequence, any bit shift only affects the phase spectrum, and not the amplitude spectrum, of a Fourier transform represented in polar coordinates. The amplitude spectrum stored in the thumbnail can therefore be matched without any knowledge of the unknown bit shift caused by registry errors between the original scan and the re-scan.
摘要翻译：通过将通过在纸，纸板或其它物品上扫描相干光束而获得的一组数据点进行数字化并测量散射来获得数字签名。还通过数字化该组数据点的傅里叶变换的幅度谱来确定缩略图数字签名。因此可以建立数字签名及其缩略图数据库。文章的真实性可以稍后通过重新扫描文章来确定其数字签名和缩略图，然后搜索数据库进行匹配来验证。在傅里叶变换缩略图的基础上进行搜索，以提高搜索速度。速度得到改善，因为在伪随机比特序列中，任何比特移位仅影响以极坐标表示的傅立叶变换的相位频谱，而不影响幅度谱。因此，存储在缩略图中的幅度谱可以匹配，而不知道由原始扫描和重新扫描之间的注册表错误引起的未知位移位。
