Abstract

PURPOSE:To reduce number of connection between a motor and a sensor by a method wherein using a rotary encoder which is provided on a same shaft of a DC brushless motor and is varied in widthes of slits, a position information, a speed information and a position information for head switching are drawn out. CONSTITUTION:Slits in a rotary encoder 16 are divided into smaller parts to get informations for a position control, a speed control and a head phase control. An output light from a light emitting element 17 is applied on a light receiving element 18 through the slit, and it is converted into a electrical signal. This electric signal is converted into a logic signal through an amplifier 19 and by an A/D converter part 20, it is converted into a six phase signal for motor driving by waveform conversion at a logic part 21, and it controls a three phase driving coil on its application through a predriver 10 and a driver 9. The speed signal and the position information for head switching are applied on a phase control input terminal 26 of the predriver 10 and a speed control input terminal 27 through logic parts 21-23, through a phase comparing circuit and a speed comparing circuit that are not illustrated after passing through a head phase signal output terminal 24 and a speed signal output terminal 25.
