Abstract: The write cache control unit stores data in the buffer memory in response to a write command from a higher-level apparatus to respond a normal ending of the command, and then writes the data in the buffer memory on the disk medium. The vibratory environment measuring unit measures an environment under which a vibration is applied to the apparatus. When an abnormal vibratory environment under which writing on the disk medium likely fails is determined from a measured environment by the vibratory environment measuring unit, the vibration countermeasure processing unit disables the write cache control unit, and if the write cache data remains in the buffer memory at that time, writes the data in the temporary storage area, and if the abnormal vibratory environment is not determined, writes back the data to the original position on the disk medium.

Abstract: A data storage device includes: a recording medium that has two or more system data recording areas where system data are recorded on a multiple basis, and a user data recording area where user data is recorded; a head that writes and reads data into and from the recording medium; and a system data update control section that causes the head to update the system data on the recording medium. The system data update control section causes the head to record new system data on a multiple basis in another sub-record area that is alternately selected at each update to the new system data over the two or more system data recording areas when each the two or more system data recording areas is divided into two sub-record areas, and read the new system data from the another sub-record area to confirm that the new system data is recorded correctly.
