Abstract
A spindle motor driving method and apparatus are provided. The method includes detecting the rotation speed of a spindle motor and heating a hard disc drive until the spindle motor reaches normal rotation speed. Accordingly, it is possible to enable the spindle motor to quickly reach the normal rotation speed by controlling the heating of the hard disc drive without using temperature and/or viscosity measurement sensors.
