Abstract
According to one embodiment, a magnetic disk device configured to record data in a shingled-recording manner, wherein the device performs sequential write in a shingled-recording area on a magnetic disk such that data to be written in a write target track and data located in a one-forward track of the write target track are received on a volatile memory and then write with respect to the write target track is performed, and upon occurrence of an unexpected power cut, the device stores data unwritten in the shingled-recording area out of the data received on the volatile memory in a nonvolatile memory.
