Abstract
According to an embodiment, a magnetic disk is provided with a first area including a plurality of blocks and a second area designated as a write destination by a host. The first memory is a volatile memory that receives write data received from the host. A controller estimates a degree of influence of ATI for each of the plurality of blocks, and sets a first block in which the degree of influence of ATI reaches the first threshold value and two blocks adjacent thereto to be unwritable. The controller selects one of one or more blocks which are not set to be unwritable and have free space among the plurality of blocks, and stores a copy of write data in the first memory in the selected one block at least for a period until the write data is written to the second area.
