PURPOSE:To increase number of winding of the coil of a magnetic head and increase output by forming the magnetic head and an electronic circuit that processes signals from the magnetic head on the same printed circuit board. CONSTITUTION:A connector cable 4 transmits signals processed by a magnetic head unit 2 to a circuit substrate 5, and the circuit substrate 5 makes secondary processing of signals processed by the magnetic unit 2, and control of a spindle motor 6, a stepping motor 9 etc. The spindle motor 6 rotates a magnetic disk, and a needle 7 connects a carriage 3 to the screw 8 of the stepping motor 9, and the stepping motor 9 drives the carriage 3. Thus, by forming the magnetic head 1 and an electronic circuit 5 that processes signals from the magnetic head on the same printed circuit board, generation of floating capacity caused by connection of the magnetic head and electronic circuit can be shifted to high band side of resonance frequency, and the number of winding of the coil can be increased, and output is enlarged. |
