磁盘装置及控制方法
摘要：
本发明提供磁盘装置以及控制方法，具备：具有第1区域及第2区域的盘；对上述盘写入写入数据的头；将从外部输入的上述写入数据存储到第1容量为止的缓冲器；控制器，其取得基于由上述头向上述第1区域转移保存上述写入数据的时间的第1处理量和通过从上述缓冲器向上述第1区域转移保存上述写入数据而改善的第2处理量，比较上述第1处理量和上述第2处理量，基于上述第1处理量和上述第2处理量的比较结果，判断是否将上述写入数据向上述第1区域转移保存。
摘要（英）：

According to one embodiment, a magnetic disk device includes a disk including a first region and a second region, a head configured to record write data to the disk, a buffer configured to store the write data up to a first capacity, and a controller configured to obtain a first processing amount based on a time to save the write data to the first region by the head and a second processing amount improved by saving the write data from the buffer to the first region, compare the first processing amount with the second processing amount, and determine whether the write data should be saved to the first region, based on a result of the comparison between the first processing amount and the second processing amount.
