摘要： According to one embodiment, a disk medium rotates in a first rotation state when access is given, and rotates in a second rotation state lower in rotation number than the first rotation state when access is not given. A controller receives, from a host device, a read command for reading first data stored in a first buffer, when the disk medium is in the second rotation state. The controller transmits the first data from the first buffer to the host device, without causing a shift into the first rotation state, and then shifts the disk medium into the first rotation state after completion of execution of the read command.

摘要： A disk device includes a recording medium having a plurality of recording surfaces, where each of the recording surfaces includes a system region for recording system data related to an operation of the disk device, and a controller configured to control recording of the system data in the system region. The controller is further configured to divide the system data to be recorded into a plurality of portions of divided data of the same size. The controller is further configured, after recording of a first portion of divided data in a first system region disposed on a first recording surface, to start recording a second portion of divided data in a second system region disposed on a second recording surface. The recording of the second portion of divided data is started after a switching time, during which switching from the first recording surface to the second recording surface transpires.

摘要： According to one embodiment, a magnetic disk device includes a disk, a volatile memory, and a controller. The disk includes a save area and a user data area. The volatile memory includes a cache area and a cache management area. The cache area is used to store, as write cache data, write data specified by a write command to be written to the user data area. The cache management area is used to store management records for the write cache data. The controller writes write cache data indicated by the management record and not having been written to the user data area, to the save area in accordance with a synchronize command.
