摘要： PROBLEM TO BE SOLVED: To prevent off-tracking of a head on a disk by suppressing deflection of a motor base.
SOLUTION: A brushless motor 10 with a core is provided for rotatably mounting a disk D on which information signal is recorded or reproduced with a head 34 movable in radial direction of the disk. In a stator core 13, teeth parts 13b are protruded radially from an annular core part 13a by a multiple of the number of coil driving phases. When a motor driving coil 14 is wound on the teeth parts 13b of the stator core, coil clearance holes 11b1 in which the coils 14 wound on the teeth parts are inserted are formed on a motor base 11, decreasing the quantity by the number of coil driving phases multiplied with N (N is natural number) to the number of teeth parts. Meanwhile, the number of turns of motor driving coil on the teeth parts corresponding to the portions where no coil clearance hole is formed is set to be zero or less than the number of turns of motor driving coil on the teeth parts corresponding to the portions where the coil clearance holes are formed.
