Abstract
Embodiments in accordance with the present invention provide a disk storage device and a control method for the disk storage device, which are capable of precluding an off-track write resulted from stick-slip caused by thermal distortion. A magnetic disk device is provided with a magnetic disk, a head that makes a writing to the magnetic disk, and a temperature sensor that detects the temperature inside of the magnetic disk device. Moreover, the magnetic disk devicechanges determination requirements for use to make a determination whether or not to prohibit the writing by the head to the magnetic disk based on a measurement temperature detected by the temperature sensor and an amount of temperature change calculated using the measurement temperature.
