摘要： Disclosed herein is a disk drive in which servo-sector addresses are reproduced from a disk, a target data sector to be accessed is specified, and data is read from or written in the target data sector. The servo-sector addresses are recorded on the disk and randomized in accordance with a specific translation rule, thus arranged in an order different from the order they should be arranged in the same cylinder. The disk drive has a read head and a CPU. The head reads the randomized servo-sector addresses from the disk. The CPU refers to a back translation table, translating the servo-sector addresses back to the original servo-sector addresses. The CPU then checks the continuity of each servo-sector address with respect to the adjacent ones. If the servo-sector address has have no continuity, the CPU determines that the servo-sector address has an error.
摘要翻译：这里公开了一种磁盘驱动器，其中从盘再现伺服扇区地址，指定要访问的目标数据扇区，并且从目标数据扇区读取或写入数据。伺服扇区地址被记录在磁盘上并根据特定的转换规则随机化，因此按与它们应该排列在相同气缸中的顺序不同的顺序排列。磁盘驱动器具有读取头和CPU。头从磁盘读取随机的伺服扇区地址。 CPU是指一个反向转换表，将伺服扇区地址转换回原始的伺服扇区地址。然后，CPU检查每个伺服扇区地址相对于相邻的地址的连续性。如果伺服扇区地址没有连续性，则CPU确定伺服扇区地址有错误。
