磁盘装置及其记录方法
摘要：
本发明的实施方式提供即使产生写重试处理也无需重新进行以磁道为单位的纠错处理用的奇偶校验扇区的计算的磁盘装置及其记录方法。根据实施方式，磁盘装置向缓冲存储器输入要向磁盘写入的预定的写数据，并以扇区为单位生成奇偶校验缓冲器的控制信号、写选通、基于逻辑扇区编号的种子值。另一方面，以扇区为单位取入写数据并施加加扰，依照写选通依次写入到磁盘的预定的磁道的扇区，根据奇偶校验缓冲器的控制信号开始进行预定的磁道的奇偶校验运算，运算加扰处理的输出与奇偶校验缓冲器的输出的异或并利用奇偶校验缓冲器暂时保存，在预定的磁道的写入完成时，将暂时保持着的奇偶校验运算结果写入到磁盘的奇偶校验扇区。
摘要（英）：

A magnetic disk device includes a plurality of tracks and a controller. The controller receives write data to be written to a first sector of a track, generates a first data string based on the write data and a logical identifier for the first sector, attempts to cause the first data string to be written to the first sector, determines whether a write error has occurred while the first data string is written to the first sector, generates a second data string based at least in part on the first data string, and in response to determining that no write error has occurred while the first data string is written to the first sector, writes a parity data string that is based at least in part on the second data string to a second sector of the track that stores parity data for the track.
