Title: Spindle motor driving circuit for magnetic disk device
Inventor: HATTORI SATORU
IPC: G11B19/20
Filed: 1989-04-20
Abstract: PURPOSE:To prevent trouble due to attraction from occurring between a magnetic head and a magnetic disk by actuating a spindle motor by raising a motor diving voltage gradually by utilizing the temperature-resistance characteristic of a resistance body. CONSTITUTION:A thermistor 120 connected in series between the emitters of motor driving switching elements 11-13 and a motor driving power source has a high resistance value at low temperature when the motor 60 is at a stop, but varies to a low resistance value by self-heating with the starting current at the start of the motor 60. When the spindle motor 60 is actuated, a voltage applied to the spindle motor wiring can be raised gradually from a low voltage because of the characteristic of the thermistor 120. Then a motor control circuit 100 turns on a soft/normal switching element 53 a certain time later to apply a rated voltage to the spindle motor winding, thereby starting normal operation. Consequently, the trouble due to attraction is prevented from occurring between the magnetic head and magnetic disk when the spindle motor 60 is actuated.
