作者提出了一种方法，用于编码磁盘阵列的方式，该信息是防止两个磁盘故障。编码需要两个冗余磁盘，这种性能是最佳的。编码和解码电路只需要异或运算，这使它们比涉及有限域运算的其他方法（如里德-所罗门码）更具优势。<<ETX>>
The author presents a method for encoding an array of disks in such a way that the information is protected against two disk failures. The encoding requires two redundant disks and this performance is optimal. The encoding and decoding circuits require only exclusive-OR operations, giving them an advantage over other methods involving finite field operations, like Reed-Solomon codes.<<ETX>>
