    • A magnetic disk apparatus that uses a head to write data in a plurality of unit areas arranged in an adjacent relationship to each other on a surface of a magnetic disk, and includes: a first recording section that records, in a RAM, the position of a unit area which is a target of data write; a first counting section that counts the number of times of data write operation performed for the unit area corresponding to the position recorded by the first recording section; and a second recording section that records, in a non-volatile storage medium different from the RAM, the side position which is the position of a unit area adjacent to the unit area whose number of records counted by the first counting section is more than a predetermined value.
    • 一种磁盘装置,其使用磁头在磁盘的表面上以彼此相邻的关系布置的多个单位区域中写入数据,并且包括:第一记录部,其在RAM中记录 作为数据写入目标的单位区域; 第一计数部分,对与由第一记录部分记录的位置对应的单位区域进行数据写入操作的次数; 以及第二记录部件,其在与所述RAM不同的非易失性存储介质中记录作为与由所述第一计数部件计数的记录数量大于所述单位区域相邻的单位区域的位置的所述侧面位置 预定值。
