摘要： In order to raise the drive efficiency of a spindle motor that drives a recording disk for information recording and hence to achieve power saving/lowering of noise level of the information recording device as a whole, in an information recording device wherein a synchronous motor is employed as the spindle motor that drives the recording disk for information recording, and wherein the head is accessed for purposes of reading or writing information at a designated position on the recording disk, with change in mechanical output of this spindle motor, the mechanical output value sought for the spindle motor is found from the head position on the recording disk before and after access, and the thus-found mechanical output value is used to adjust the electrical input to the spindle motor.
