Abstract
A storage unit is provided with at least one head for reproducing servo information from a medium, a processing part for carrying out a servo process to position the head with respect to the medium, and a setting part for setting a ratio of a first time with respect to a sampling time smaller in one of a data read state and a command wait state than in a data write state. The sampling time is made up of the first time in which the servo process is carried out by the processing part, and a second time in which a process with respect to a request from an external host unit is carried out.
